Adding micro to reduce a unit performance is not really "elegant" in my book especially in late game where things happen faster.
Please tell me how do you come to this conclusion. There was no micro added
to anything. There was no mention of "we are making it so that Brummbar requires micro now as to reduce it performance" or any dumb shit like that. Micro just exists in every game. And you can have more control over certain things using micro.
Your perseverance on labeling an option
to micro things as "disadvantage\nerf\performance reduction" is mind boggling. Not a single player here finds it as such. And you keep pushing and pushing this agenda. It's not happening man.
Can you provide some solid facts plese, that having ability to micro things was intented as a gatekeeping or "unit performance nerfing" mechanic? And not a mechanic that actually gives more control to the player?
