I really enjoyed the way MCH played with Gauss barrel and you can tell the class was designed around it and hate playing MCH in 50 roulette cause it feels brain dead to play. with stance dancing and managing ammo correctly it did create quite a wide skill gap and you could usually tell when someone knew how to play MCH well and I can see SE wanting to raise the skill floor but removing Gauss barrel wasn't correct way of achieving it imo.

the changes I personally wanted to see was to make the AOE turret similar to the Rook turret and just fire AOE shells rather than have to constantly move the turret when tanks decided to pull everything out of peoples AOE's and the real wishful change I wanted to see is the turret act similar like a pet and hovers around you and follows you when you move.

I'll still level MCH first to see how the new changes play out and if we have to manage heat instead I can only hope it plays similar to Innovative Ordenance Mercenary in SWTOR
