so as a way for the Sc2 team to generate more revenue from Co-op, so they may continue releasing content for it I’m proposing each commander to slowly receive simple cosmetic DLCs for all kinds of things in their kit such as hero skins, different firing animations for units, different calldown skins, different colored particle effects, and even different sound effects. Like give each commander a loadout tab where you can equip/unequip these different skins/effects. All of these different cosmetics could even have different rarities, from common to legendary. Maybe some could even be received by chance at the end of a game while other require you to buy them.
to give a few examples:
Karax - Different color Purifier beam, new shadow Canon effect, different colored energizers, New nexus skin.
Raynor - Different Hyperion skins, different marine skins, Banshee calldown skins.
Kerrigan - Broodwar Kerrigan skin, Redhair Ghost Skin, WoL kerrigan skin, different Hydralisk skins, different Hydralisk firing sound effect.
Mengsk - New contaminated strike Gas color, new Earthspilitter explosion effect, new trooper weapon skins.
Alarak - New Destructive wave animation, New Structure overcharge color, New Alarak Helmet skin.
