CoOp gameplay balance

Well, there's lots of heroes that are tailored to be damage dealers, especially bruiser/assassin types that go up close and personal, their damage output is gah. So then why give opportunity to boost them even more with items like Mejai and Sword of the Occult, for CoOp that's like turning super easy mode on. Usually it's 1 or 2 people that opt to do that in a game, but that's enough to render the others in the team useless, or at best fodder for the bots. If you picked a support and someone went with one of those items then GG, you can just afk, you're not needed anymore, but you can't since you introduced penalties for that.

Therefore I suggest you remove those items from Co-Op matches, if not from all difficulties , then at least from intermediate.
