I agree with the OP. Jump like FFXIII where it's action oriented in certain spots to give us that super hero-esq feel. It's a game, we don't want it to be overly realistic after all...if you do want a super realistic game, there's always real life. :-P

So I agree there's no point in people spamming jump. Especially with so much being server side, it's just gonna crash people having all that extra data just to see 100 people jumping around in town like idiots who have no idea how the S&R packets are working. Having it as a controlled action would be nice though.

If they really wanted to make a tactical use for it in battle, you could always have the ability to jump on huge mobs and attack the back of the neck/head, like on the great buff and stuff. Of course if they did do that I'd like to see it be class specific to LNC or MRD or something.
