This is talking about spawn camping and resource camping, not camping(sitting in one spot). And yes spawn camping is a problem.

Camping is part of nature, watch any living thing that hunts.

Fighting games don't have "camping" characters. They have zoners...characters who have a more of a hit and run tactic. Blazblue CT in particular had Nu-13, then Hazama in CS. They both specialise in ranged attacks. I haven't played street fighter, but I imagine that is the case for Guile, because most casual players tend to hate those who use zoners as these characters can be tough to beat without a sound strategy.

But fighting games are different than FPS games. Almost every playstyle in fighting games has a counter, like a rock paper scissor game. Each character has a good and bad matchup. The camping stated here is related to FPS games where I can sit behind a certain point of a map and the enemy players will keep spawning at the same spawn points, letting me just camp a line of sight and pick people off as soon as they spawn. This is a major issue that most FPS games try to fix, either by allowing you to choose where you spawn (Battlefield), or better spawn programming or temporary spawn invincibility against killstreaks (Call of Duty). I don't know if any game has perfectly nailed it.

Why the heck would you ever run around with a shotgun in hardcore mode?

HC gives you 30% health, making almost every gun in the game a 1 bullet kill up to extremely long ranges. In other words, every gun becomes a shotgun. Except the only difference is that assault rifles, smgs and lmgs can spray bullets all over the place and kill you at long ranges while shotguns have a low fire rate and miniscule range. If someone can do good with a shotgun in hardcore, I'd give them props for being a skilled player.

But yes, one man army noob tubes ruined COD MW2. If not for that one stupid tactic, that gave would have been one of the best shooters of all time.

i see people all the time running around with shotguns you dont have to aim with them just pull the trigger in the general direction of a player and thier dead.  but i did type running around i didnt mean running the people i see with them normally are just sitting inside a building watching a door the whole time.

The is what is always over looked about campers. You say they don't get lots of kills. I say they don't get lots of deaths. Most good campers finish the match with something like 7/2 or 10/3. That's a +5 and +7 meaning they actually helped the team more than a shaggy who gets 17/15 or 17/19. Most shaggies have a negative K/D ratio which in a game like COD, ends up hurting their team WAY more than helping it since there's a short time limit.

Overall, camping is a better strategy.

TF2 spawn kills with a demoman,pyro and a medic team are the best! Camp galore!
