I sware... almost everyone is doing it now, even Nxon. This why I just stick with the SPAS and Carbonizer..
Because most hoppers are usually bad in aiming their gun. Hopping prevents damage because they are harder to hit. Only 1% of the hopping population has good aiming while hopping, making them incredibly annoying to deal with. The rest, are just trying to compensate for their bad aiming.
Just practice a little bit using the HVS45. After a while your accuracy will go up and you will notice that it doesn't matter anymore whether they are hopping or not. Switch over to the USP and kill some bunnies....
My guess is that they saw somebody do it and copied them.
By the way, whatever happened to goodofwa? That guy used to drive me nuts! (My apologies if you're actually here, I could just never figure out how to counter you) --- The Wii Shooter Unleashed! Wooof! Wooof! Conduit2FC(36): 3354-2948-5226, (38): 4814-7986-3261
Bunny hopping has been going on for a while now, even since before I retired or even played the game, and seeing as how I got the game day 1; yeah.... --- Chariloe http://www.youtube.com/user/Chariloe?feature=mhee
