Why is jumping always associated with WoW?

[Tiraelina]

The only kind of limitation I ask for is no jumping in battle. Reason I mention this is because in Aion Rangers would exploit jump to cancel combat animations and that became the only accepted way to play the class. Single handedly made me not want to play the class.

The way Aion handles animations isn't the way every game handles animations. It's the only MMO I know of that has everything tied directly into animations as much as it does. Clipping/Weaving applies to a lot more than just Rangers.

Meanwhile every other MMO doesn't really care because jumping is just that, jumping. It's not interrupting anything except casting.
