I honestly think they should simply allow us to stop the OH somehow. Heat generation is a little too slow, if they want it to be this way to help rookie mch they should at least give us more tools to control it and force OH when we need it. Overall though the dps buff is there, I'd say at least 100 dps more than before, but I'm not sure this is enough. This barely puts mch and brd on the same level, but brd is still the superior job when it comes to anything else basically.
