Yeah, some of those cosplayers are a little too attached to who/what they are trying to emulate.  Yaoi-con, on the other hand, would be much more interesting.
 
 
 
Somebody mentioned FFXII espers.  FFXII espers aren't made for ultra-strong attacks.  I read someplace that they're more for finishing off hard targets, some bosses, and crowd control than actually using them often in battle.
 
Still, I love how characters in FFXII are so customizable with the Liscense Board.  The instruction booklet actually has a spot where it says it's sometimes best to make characters specialized in a certain area rather than balance everyone out.  Anyone else find themselves in this combonation:
 
Vaan/Basch as tanks and damage dealers with little magic, usually equipped with sword/shield, spears, katanas, or 2hand swords.
Balthier/Fran are usually thieves, support, the main technick users, and backup attackers using bows, guns, poles, and sometimes knives (ninja swords are usually useless because of their shadow element).
Ashe/Penelo are almost always my mages with all magics, both healing and attack, and always use maces/shields, rods, and sometimes staffs.
 
Well, that's what I always do.
