Wow, forgot all about Soldier of Fortune. Anyway, coming from COD this game is going to be slowwwwwwwww. It's really all about patience, so if you're not cool with staring at a doorway for 2 minutes, literally, then you may not enjoy it much. Also, the recoil is insane (realistic) so unless you're using the shotguns, aiming and bursts are the only way to get kills. It is fun tho if you're into this kind of shooter. Watch a bunch of YouTube vids first.
As far as patch support, there's been one big one so far, but it did next to nothing to fix friend/squad server issues and very little for disconnects,etc. I think it's worse on the Xbox One tho. Hopefully January's patch is a giant leap in the right direction. But seriously even as pissed as I get at the servers, being disconnected, etc, I'm still stupidly addicted to this game. I can't stop playing. It never feels like a grind, it's just pure enjoyment.
