Idea 1) If I have to add something, I would add a colosseum like in FFVI. Groupal and individual. You get a bunch of dailies and weekly allowances. You earn points by killing several and random bosses with a cap system like in FFVII. This system includes bosses and monsters from previous raid content. Depending on the monster, is the amount of points you earn and you can exchange said points for vanity.

Idea 2) Class wise, I don't want anything else, since my 2 favorite jobs are here: DRK in 3.0 and PLD already exists. If I could suggest a class, I would ask for a FIGHTER. Yeah, a melee DPS with a sword.
