We have a mech pvp and alot of heros dont need timing to use so thought of this one
Bronze skill. Weapon Jam - Jams opponent weapon denoting all remain ammo weapon has as damage. Well timed skill just before Panzer Dogface uses main skills would be a great counter.
Silver Skill. Bubble Covers hero in an aborbing shield healing Hero instead of damaging them.
Gold Skill. Weapon Damage Now Causes Stun and damage increased
Platium Skill Bubble now reflects heal to random allie
Think something like this needs skill and timing to maximize effect
