I actually wouldn't mind if they removed the rank requirement on PvP gear completely, instead change that "Materia effect active during PvP only" part to "Materia effect inactive if PvP rank is below X". That way your reward for PvPing a lot is effectively "free" crafted gear...

Mostly just want that because of inventory issues though... Kinda hard to have everything in the game leveled and then add sets for PvP... If PvP gear became viable PvE gear with Acc melds after reaching a required PvP rank that'd at least help... Not like the materia effects are even active in PvP these days anyway...
