Alright guys, lets be honest. All this talk on which perks are op and which are not as well as which weapons break the game or are over used is ridiculous. It all comes down to one thing.
Stealth enhance.
Imagine if everyone who ever picked up the game had it at level 3 when they first started. Stealth enhance is the most op perk so why don't you guys just ban that. Then we might as well play COD.
