What if marauders could alternate between their normal concussive shells and the firebat flame attack??
Well then people would say terran is imba so this is a no. We don’t like balance whiners here.
I had actually suggested a similar mechanic for a SC Warrior Hero in Heroes of the Storm, before Blaze was introduced.
However, I’d imagine carrying the fuel tanks, sprayers, launchers AND microfabricators (for grenades) would make the heavy infantry even heavier.
It’s a cool idea, I will admit it but I don’t think blizzard should add it.
