Of course with Ifrit, I can bet the devs weren't planning on everyone having all 50's, (or at least the abilitiy to make it that way relatively quickly) with their tier II and III abilities to further support them. Sentinel handy? - take a few hours and go get it. Cure III useful, but your CON is Lv2? - Eh, throw a rock at a Lv50 who's bored and take care of that.

Too much easy is what will eventually break this game for good, if it hasn't already.
