.. Anima gives everyone the ability to teleport right? So .. why restrict it to one job? That's silly
There's a fair recharge on anima, so those who teleport everywhere will eventually run out and be forced to walk.
I'm pretty sure we don't want to force people to walk, or allow this stupid idea of WHM unlimited teleports. Anima allows for a system that can balance out teleporting/walking.
It really doesn't ruin the game at all... I use it all the time when I teleport with parties to La Nosca from Ul'dah

saves us time and lets us get on with what we want to do.
-- Also, Anima not feeling very 'Final Fantasy' to you? >:[ I wonder what people said about Final Fantasy VII (how different it is compared to the previous final fantasys)?
