It's annoying when everyone is trying to enjoy a match but there's some numpty going outside of the map boundaries to camp, it's neither big nor clever and it sure as hell ain't cool. What makes it even worse is people do it when there's really no need to e.g

5vs5 Plunder match 3 members of one team crash or leave. Team B all armed with Headsets conclude it would be a good idea to trap the treasure outside of the map and try to wrack up their kill count...great plan, except me in Team A ends up getting the most kills in the match and my partner getting the 2nd most, so my question is, What was the point in doing this? yes you won but your K/D ratio dropped (thanks for the free BBQs and Kick Off medals btw).

What's even more annoy is when in Deathmatch, after getting a perfect score only because they went out of bounds, some moron has the ordacity to then brag about it, calling everyone names, this seriously needs to be fixed as it's killing the fun for me.

thanks for the warning, thought about MP for U2 but I wasn't sure what kind of B.S. to expect...now I do

Maybe they need to invest in moderators for PSN like Microsoft has for Live with a report system for bad behaviour? I remember some video posted about that from 4chan or somewhere.

Welcome to online gaming....most online games have problems like these.

Best thing you can do is just avoid them and file a complaint on them and hope the mods ban them.

CHEATING IN A VIDEOGAME?!?! The nerve of some people! Anyways, PSN really needs a report button. If you want cheaters though look no further than Mario Kart Wii's time trials.....

Mario Kart cheating is not an issue - the time trails no-one cares if someone has a 15 second race time. In multiplayer there's no amount of cheating they can do that can stop a good player from winning.

wow I haven't ran into anything like this yet, but now I know they're out there I'll just quit the game if anything unusual happens.

How often does this happen?

I've put in 200 hours into the game's multiplayer, and I have to tell you that glitching is not as prevalent as it was before. Naughty Dog has fixed alot, and I mean ALOT, of glitches. Though you will always find assholes who try to figure out a new one as soon as an update is released. As for treasure-camping, treasure-glitching, and everyone simultaneously leaving the match, all I have to say is that there still is a good amount of work that Naughty Dog has to put in to fix the multiplayer. 

For whats it worth, I like it. Nothing in the game is TOO overpowered and everything seems quite balanced. Co-op objective matches are a blast to finish with friends, especially on harder difficulties which require a decent strategy. There are a good number of playlists to play on, which does make the game more fun and exciting. The only BIG issue that I've come across are the online connection errors. GOD, they suck! Error this and error that. Once it took me 20 mins just to log-in online; why did it take that long you say? I got the "Error Syncing Models" error over 7 times.

Other than that, It still is a blast to play :)  

Me hate errors too!
