What I intend to discuss is what I see as the most unforgivable flaw in Call of Duty:  Modern Warfare 2. 

But I'm going to take my sweet time getting there. 

What it's not: 
--I bet a lot of you entered this thread wondering whether it was going to be the Javelin glitch, which to the uninformed let you make your body a booby trap that set off a massive explosion upon death, or the Care Package glitch, which let monkey-knifers run about twice as fast as their already stunning speed.  In fact, not only is it neither of these, it's not any glitch or even ALL glitches, because at least Infinity Ward fixes those, if belatedly. 

--It's not monkey-knifers in general (marathon, lightweight, commando, constant knifing), nor is is nuke boosters (two guys on opposite teams conspiring to give one of them the nuke, basically throwing the game), campers or even fucking spawn campers. 

--It's not even the fact that the game can and will spawn you into an ongoing enemy airstrike, allowing the same airstrike to kill you two or three times.  Yes, this has happened to me.  This is worse than just spawning you right in front of an enemy to let him shoot you, this is the game literally spawning you into an area it KNOWS is instant, certain death for you.  But even that is less offensive to me than the following. 

What it is: 
The problem that I hate the most is that THE CLASSES SUCK.  Wait, no, that's misleading.  I mean, the classes themselves are fine, well, except for "Overwatch" because the rocket sucks (can't take down a Harrier in one shot, which is all you get with the AT4, and WTF is up with that anyway), and except for "Scout Sniper" with Scrambler on which gives away your existence at short range and doesn't hide your presence when you fire at long range with your sniper rifle (secondary weapon, a friggin' pistol, is already silenced).

Anyway.  The problem I hate the most is that there is no decent default class for evading or destroying killstreak vehicles. 
--Overwatch is the only default class that gets any sort of rocket, and as I said I believe the AT4 is incapable of taking out even a Harrier in one shot, which you probably won't even get since it can see and kill you (I'm a killstreak magnet, 75% of the time a Predator can see me it kills me).  Would it have killed them to give Overwatch the RPG which gets 2 shots (or the Stinger which gets lock-on as well as 2 shots at the cost of anti-personnel capability)? 
--Likewise, the only default class with Cold-blooded is not acceptable for most situations.  Sniper rifles have limited application compared to any other primary weapon except the Riot Shield, and the secondary weapon is only a pistol.  If it was a machine pistol or even a shotgun I wouldn't have as much of a complaint, but it's not.  Don't get me wrong, I LOVED pistols in CoD4 and I was awesome with them; and they're fine in MW2 for some purposes, but they lose miserably to machine pistols at medium range which is what a sniper rifle class sorely needs, and of course it loses out to shotguns at point blank.  And your ability to sneak around is compromised by Scrambler, further limiting your options when a Chopper Gunner is tearing up the landscape outside. 

[edit:  Cold-blooded perk and Stinger missiles are unlocked at level 25 and 30 respectively IIRC.  You are seriously screwed until then if aerial killstreaks are called in on many, many maps.]

Every time I prestiged, I was brutally reminded of the way Infinity Ward chose to handicap low ranking players, precisely the players that are least able to labor under that handicap.  Sure, everyone loves to get a killstreak and mow people down, but if that comes at the price of noobs having to literally choose between letting you mow them down with your killstreak because they can't hide or letting someone else mow them down because they don't have a decent all-purpose gun, it's a disgrace that Infinity Ward has overlooked this problem. 

What do you think?  Do you agree?  What would you say is the worst problem with Call of Duty:  Modern Warfare 2? 

Maybe you should have had an option for all the above? :P

I played it during a free weekend on Steam and got bored of it really quick.

All of the above is not only a cop-out but the designated "hater" option which would skew the poll. 

But what I mean by cop-out is that you're avoiding choosing which one of the problems is actually worse.  If you can't decide between them, that's fine, just don't screw up the poll please. 

The maps themselves are terrible and boring. Pure campfests.

The game is full of people who spam grenade launchers. Fucking annoying.

The issues you've listed along with the, from my experience, extreme annoyance of joining and playing in rounds because of the P2P only multiplayer are why I would want that kind of option. In fact, the P2P is one really good reason why I would have selected 'something else' no matter what.

I can see what you're saying, but in my opinion I was generally dissatisfied with the multiplayer experience so I don't think I can settle for just one issue being the worst. To me, they all add up.

I loooooove being a witch ^.^

It's so much fun.

Those are some problems, i get annoyed most by the signal biased. I moved from my house with a great connection to one with not so great and its just funny how everything from your gun damage to granades anything depends on your connection. So now it takes a ridiculous amount of rounds to drop anyone yet a 4 bar guy can kill me with 2 bullets from a m9. They need to make it a set system so no matter your connection its the same. Just makes it really not a fun game. I wish they would return to their roots and make it a level playing field for everyone.

The 4 hour long single player mode was my major gripe. I buy a lot of gmaes so play single player most and dont see value in paying €60 on a 5 hour long single player mode.

I get you, but that's a different question than the poll asks. 

As for P2P, CoD4 had a terrible, terrible setup that stopped the game anytime the host dropped/quit, and if it happened at the start of the game (which seemed to happen in about half the games) the resultant draw counted as a loss.  Words fail me. 

MW2 doesn't quit out when the host drops, which  makes it indescribably better for me.  Maybe my standards are low, but ignorance is bliss.  Although I have noticed the connection bias mentioned in another post. 

I'm aware of that. In my experience with Modern Warfare 2 on PS3 and PC, host migration usually isn't a very smooth transition. Most of the time there is a tremendous amount of lag (enough to make it unplayable in some cases) in the time prior to and after the migration and I have had to sit through a number of long waits only to get a 'migration failed' which boots everybody back to the lobby anyway.

It's a step in a better direction compared to Call of Duty 4 on the consoles. However, my gripe stems from the PC version where Call of Duty 4 uses dedicated servers and Modern Warfare 2 forces P2P on everybody where, in my opinion, there wasn't a problem that the P2P would be fixing.
