I'm not the first one to come up with these suggestions, veteran players have been suggesting these very same things for a long time now, including former SkBr player
@Brandis. who is quite experienced in playing in the competitive community.
The goal is not to make it an even playing field at all, its to encourage a commander playstyle where people control their troops and the focus is on unit control similar to battles in the singleplayer campaign, only instead of an Ai commander the commanders are players. This is what the developers have in mind for captain mode and not the skirmish with extra lives that it currently is.
I have no doubts that rambo can be dealt with, this is not the issue at all. The issue is that rambo promotes the wrong type of playstyle that is too focused on player combat instead of being a commander of troops like it should be.
But don't just take my word for it:
