Lol that weirdo dude is back I love him
Anyways, since most mobs hit physical. By wizards taking warrior as a Sub, they can minimize the damage taken from mobs > increasing their survivability > decreasing the number of deaths > decreasing the chance of screwing up the party > maximizing the damage by having 8 damage dealers and no buffers > increasing the mob killing rate and thus gold and drops.
Thats pretty much it.
