Very cookie-cutter linear progression. They could at least allow end-game gear to be meldable so you could slightly customize your gear with materia (and I don't mean crafted items). A skill tree would be interesting & give some customization as well. More customization = better long as it doesn't get ridiculous. It's a decent game and looks amazing but the retaining factor is kinda.. eh.
My major concerns:
#1 Latency with dodging moves
#2 Tab targeting
#3 Customization & ppl looking the same.
