Oh hell yes~!
I really like this change. I'm gonna come back and try it out the moment I've got some time.
I love that you got rid of janky con income. People want con income because they like feeling like they haven't lost, like they've got a chance. But it's junk and doesn't make sense. Happy to see it gone. Con farms are bad design and bad gameplay, there's nothing wrong with people losing games as a result of losing all their important stuff.
I can see how the commander income change could address some issues with RPS. You no longer have the 1-minute rush "swell" of units that can be already out of control before you scout. However, I can see how this could fundamentally change the value of different factions (especially those centered on early game who had good matchups against those rush strategies, but now also get out-scaled faster).
