Don't really care as long as the re-design means you still effectively can do as much with your char now as before. Primarily affects DRK, PLD and BRD anyway. You don't need TP as an abstract representation of a melee job's ability to carry out actions and, besides, many jobs, like SAM or MNK, weave a lot of aether into their abilities, so I don't think it's even that silly from a lore standpoint - but again abstracted game mechanics don't necessarily need a lore grounding, per se.
