I think only Mutas, and have them “Dive bomb” in causing them to load and unload faster; and Scourge too if they bring them to SC2 Multiplayer…
What would be cool - like to switch it up and add more depth / strategy to the game, would be to do like MOBAs do, where you can ban heroes but in this have it be single player units to choose from / ban, like a “Side deck” in trading card games kinda too, choose once you find a match but before it starts… . . Maybe have to remove random it that to work - or have random players make “Pre-sets” like 4-5 and then RANDOMIZE THOSE forcing them to switch up their play style
