Ok, guess I'll add my opinion.
I don't like bunny hoppers... or mother fn spawn campers... or sniper beeches. Get killed by them all time to time. But mostly don't like hoppers. However, I will admit to hopping with a hopper if it means kill or be killed or camp the camper or sneak up on the sniper. It's all game play and meant to be fun but frustrating at times so some peeps get a little loud with frustration including myself, but just have to remember it's a game. With that said, as much as I don't like hopping, the pros of having it I think outweigh the cons of not having it, ie. being able to shoot while jumping out of a ditch or through a window and thaw when at times certain areas of a map you need to hop (more than twice) so I think it needs to stay.
Cheers all.
