Yeah, the MH-82 seemed to be tearing it up at slightly longer distances. It helped, but the turn speed felt the same, so I still got pounded on in CQC just because I couldn't track fast enough.

Then up your sensitivity, I have no problem tracking all but the fastest of targets with my heavy.

Hmm...I had thought the changes weren't yet live and only skill description had been changed.
Will check that out.

That's not the issue, I'm usually anticipating where the guy I'm trying to kill is going, so 1v1 I'll usually win unless they're using MD's and flux's or are running AR with stacked damage mods. My problem is that when there's more than one guy in front of me I'll kill one guy as their splitting up and I can't turn fast enough to catch up to the other guy who decided to run past me only to turn around and blap me.

So you're asking for a buff in uncapped rotation speed for an issue with you engaging with more than 1 target in CQC? You can be the best player in the world, if you let 2 people get in that close, you're gonna have a bad time. Hell I would argue that one of the counters for a heavy is to gang up on him so his double hp is split between 2 players pelting on him.

This. It's only people imagination that it has actually gone through, a placebo effect.
