I personally think its tons of fun.The maps are huge and spawns are a bit messy right now,but so were BO2 spawns at release,they will fix it.
AR's are definitely going to be the guns to use this game.
Health needs to be upped a bit,you get melted so quickly.
Only real gripe I have with it is it is going to SUCK for competitive play.These huge maps for 4v4's will be brutal and SnD is the only decent game mode.MAYBE Blitz but I doubt it.
