I'm not sure what's funnier, the thought of adding killer traits to this game, or the belief that they were any good in FFXI.

Killer traits have one major flaw. You have to be the target of the monster to be affected. We have two tank jobs in the entire game. We have warrior, who in classic FFXI never got ANY killer traits at all, and Paladin which got Undead Killer. Guess how many undead we fight at level 50?

So, we could give Dragoon Dragon Killer traits, but what use would it be? Unless the Dragoon is tanking, it'll never kick in. On the occasions the Dragoon pulls hate, it'll kick in very occasionally. It's not a game changer, and not really worth their time implementing.
