Anima = +HP -Rec. Which is good for survivability, but if you have a healer Anima, you'll prefer to raise it's Rec with an Elgif, for every other unit Anima is good.

Breaker = +Atk -Def. Which is good for damage dealers (Mifune is a good example of damage dealer), but the survivability is quite low.

Guardian = +Def -Rec. Goes good with mitigators, since more def means less damage recieved, for healer is the same as stated on Anima.

Oracle = +Rec -Def. Great for healers, since meanwhile more Rec they have, the better is their heal, pray that this type comes only with a healer.

Lord = Jack of all Trades, Master of None. = Good for everything, but not excels on anything, you'll mostly use Elgifs that raise the stat that you want (nuker, Damage Elgif - healer, Rec Elgif, want them to survive better, HP Elgif, etc).

This is how I see it, hope it helps.
