This is a confusing game to engage with, but I think I like it. They just clearly need to work on weapon balance and they've made the early game much less fun because of how much attachments seem to make or break weapons in Multiplayer combined with the fact it takes an incredibly long time to level those guns up to get said attachments. Which wouldn't be the worst, but man, coming off of Modern Warfare and into this one is just really rough for fairly obvious reasons. We need more maps, shotguns need some serious buffs with how bad they are currently (multiple close range shots from the Spas still don't kill, WTF), and the entire balance needs to be properly handled along with maybe even slightly increasing TTK given how absurd some of it ends up being in this game (It's rare to get into gun fights considering either you or your enemy are dead within milliseconds of encountering each other).
I like a lot of things they've done and it's fun at times, but it just needs more work.
