I'de like to point out that in a next-gen MMO there is no reason not to jump. It can't be that hard to program and just throw in. There are seriously people out there who won't play a game just because of no jumping and not that many people out there that will honestly not play a game because you CAN jump, even if they complain about it ruining their immersion. If jumping isn't a pain in the d!ck to implement (which it might be because of the weird engine they use) why not just throw it in and get a few more players. More money in their pocket when they start charging.
