I think its cause of 99's being killed by TW black mages (Freeze, and the like and the first ga III's (stonega & waterga I think) hell I heard of ppl dieing to T2 -gas its so bad.

And of course they don't list the huge issue with enmity

Its not fun dieing in carby kite solos, not fun when charmed or jug pets can't get their moves off cause the monster runs right for the player and ignores he pet.
