My main gripe is how boring the loot can be besides glamour. I think if you gave a skill system like where weapons or armor gave minor buffs, passives, or GCD's that would spice up not only the grind but also the battle system, which has its ups and downs.

Now i know this is virtually impossible to balance and implement but just little things like that would be cool. Like maybe even stat buffs for sets like how there are already some in the game. Maybe if you had all 5 pieces of some dungeon set you get NIN's huton duration increased max by 5 or 10. just small things like. or for Dragoon you have a 5% chance to replenish a jump. I know it may be stretching but i just think it give three things ( of course in my opinion)

1. more exciting combat
2. more exciting gear grind
3. a personal feeling your character is a tad different then the next Copy and Paste lvl 90 "insert class here" that you are.

Again i know this is TREMENDOUSLY hard to implement this late into the game. But it would take a B+/A- MMO to me to A++
