Let's understand something about 2k mycareer co-op....
Playing with your friend WILL NOT get you XP or badge progress towards YOUR character while playing on THEIR account side. You are only going to get Season XP and VC.
This to me, while I think 2k has a good start, also makes the addition pretty pointless. The only thing I see this being useful for is pesky badge specialization grinding. But I'm not sitting there doing all that to help a friend lol.
I actually think the way they have it designed to take over an AI special teammate is fair and makes sense, but it just doesn't do anything to benefit your friends player and because of that co-op is just a joke. I've seen mixed reviews on this with people saying that "oh it does give you progress towards your mycareer" but it actually doesn't. Added their blog site for you to see.
