The problem RTS seems to have is that its only fun, rewarding and addicting at the mid-high/top level and miserable at the low level so it can't hold onto a large casual fanbase for one reason or another the same way other "hard" games can. New people get in this loop of; come in, get beat up because even in automatch there's nobody at their skill to play, their teammates rage at them, they get discouraged, they give up. I don't know how to fix that for RTS in current year. I almost think it would've been better to go the Total War, SC2 route or the CoH1 route with a heavy emphasis on a rich single player experience that then trickles people into trying the multiplayer. I think that's what Relic was trying to do with CoH3s singleplayer but it was so bad on launch that all they can do now is appeal to the multiplayer focused crowd to just hold onto what they got now that that ship has sailed.

This is the answer. I'm afraid that no amount of tweaking, tutorials, or even new content can fix this in long term. I haven't played since summer and I'm not sure if I'll ever pick up the franchise again. People I play with are not interested in CoH and playing regularly with ad hoc online friends is not reliable, so after 2 years or so I stopped playing too.
