Ack.. sorry... A Fighting (something) would be a term used in Dota, for a spellcaster who would be using attacks more efficiently than usual, For Example a Fighting Slayer, is a spellcaster with a stun spell, and manipulating that, we increase her attack damage, instead of pumping her other nuking spells to deal damage (which costs mana)

I agree with Vyk, Aeris should be used in the front row, but only after you can be assured she won't die on you.. only then can you see her limit bar filling like crazy, and where the Cover + counter-attack materia would seem more profitable.

Furthermore, at lvl 3, when you get the Limit which effect like a Mega-Elixer.. your entire party can be spamming spells for free!! as her limit would fill your Mp as well as Hp when you use it.. Great Gospel would be a great spell to buy some rounds in a tough battle to re-cast all your spell-ups (Barrier, Mp-Barrier, Haste, Regen, etc..) without worrying about your Hp going down in those few turns you're invulnerable.

Although there is nothing i can do about her character, or the fact that she's a magnet for sephiroth's sword.. all i'm trying to say is, do give Aeris another try.. she was made part of the game anyway, and its just another way of playing the game
