about the #3, the problem with balanced those kind of summoner only come down to when the game is pve & pvp, but with FFXIV being a pve rpg game, the summon can be strong and summoner can be useless piece of crap and this will not hurt any body.

In pvp term with summoner at #3, as nowadays the summon is completely useless in dealing dmg (its dmg can be ignore by everyone and therefore useless in pve as well), the dev had tweak em down to being assit and the summoner will have their own roles as CC master
