Things that need to change

[Johnist]

It's just, the way the system is set up, I would look at slots and say to myself "Ok, its either +dex or +crit".....

Whoop-de-frickin-doo!

The materia system needs variety!

Steal Materia (Max / gear @ IL70 10%) - Chance any attack will grant you a copy of the enemy's drop.
TP/HP/MP Absorb Materia
TP/GP/MP Regen Materia
TP/GP/MP/CP Cost Reduction Materia
Status Effect Materia (Resist and inflict)
Element Damage Materia (on top of base damage)
Element Absorption Materia (Can be OPed)

Edit: Yes, I know that means on Fully crafted ItemLevel70 gear you could get between 120-130% Steal Rate if you put 10% in each piece of gear. 11 pieces of gear (Non Primry/Sub Weapon) + Primary/Sub Weapons.
