Could you define diehard FF fan?

I've played all the single player ones to max completion (except XIII, cause it's garbage) and I happened to like WoW MORE than FFXI.

Why is it so called "diehard" FF fans want a remake of the old stuff? Whether it's VII or XI they want the same old trash.

This is my new MMO and I don't want it more grindy. More grind isn't tougher difficulty. Tougher difficulty is tougher difficulty. This game is fun and different. Why is that so bad?
