This, and a few other major mess-ups in 4.86 balance were basically results of Mjolnir not listening to a word any of the test team members had said. His reasonings behind these mess-ups might have made sense to him, but it neither made sense to anyone else, nor actually worked as intended ingame.
Far as I know, this specific issue has already been taken care of and will be in 4.87 along with a few other clean-ups.
