I only experienced this heavily in WoW. Other games I can't say I really ran into it. I did use to break LoS behind walls more often though in some other games. Yeah, off the top of my head I didn't do a lot of bunny hopping in MMO pvp, only in FPS's.
But I would say that this game is incredibly polished in some places, and lacking in others. It's a "new game" but I still have fun when I play most of the time. But I'm usually drinking at the same time, so maybe that's the contributing factor.
