sounds kind of impractical, but i’ve seen comp players abuse some strange mechanics before.
think of a teammate across the hall from you… “buff” him, tractor beam into the middle of the hall, look around and pick a target, throw out heavy firepower, then tractor beam out. the current “locked aim” penalizes you for moving fast, because IMO looking around freely with a speed boost means you have almost no penalty at all.
even if you make it so no one is allowed to fire while holding the buff button, heavies huge firepower (that will come when they balance the game) will still close rank faster than they should, plus with heavy HP… they’ll be ready to aim and completely aware of all the enemies in the room as soon as they stop moving. not good. it’s almost like a controllable speed hack. the heavy’s main weakness is poor speed.
