It's a touchy subject. Microtransactions in general I don't really like, but am sorta okay with as long as they keep cosmetic. Liquid Divinium isn't really cosmetic though, although Zombies isn't a PvP, and GobbleGum doesn't give you some huge advantage. So the only thing I really dislike about it, is the whole Liquid Divinium 2 per game limitation. That was clearly put as an incentive to buy COD Points.
