Some of them already evolved into a tounerous new goblin of a subspecies (MOBAs) to fill a different niche, the rest stayed the same because they were already good as is. That’s literally how evolution works. You don’t improve RTS by drastically changing the formula, you improve then with graphics, lore, and interesting mechanics within the existing framework. If you evolve the formula then it’s not an RTS anymore.
