You know, I rather like the jump animations in WoW. But then, I actually find WoW's art style to be endearing; like a 3D stylized oil painting. And after spending three years playing FFXI, where a pebble can cause you a 45 minute detour, jumping was the single greatest thing that I'd ever been introduced to in the MMO genre.

Hate on my bunny hops, I can still do my job while spamming space bar. I played a Resto Druid -- jumping was practically part of my toolkit.
