i like the idea of the OP but some things to point out about the current skills. now please take this with a grain of salt as i do not claim to be the best MCH. that being said the key to minimizing the loss from the loss of GB after a over heat is to use two skills Barrel stablizer and overload. now barrel stablizer is kinda a no brainier it sets your heat gauge to 50 enough said. now if you use Overload durring the end of WF but before GB hits CD the dmg should be enough to drop the losses by maybe 1~2%, simply because the Overloaded turret spits out in one attack the dmg that it normally does in 30sec. yes you lose the turret but you are doing 30secs worth of dmg in one attack, or so i hear. now back to the topic i would honestly like to have a sticky turret i can throw on the MT so i dont lose dmg from the tanks moving the mobs around like headless chickens >.<
