Another problem is definatly the micromanagement. Relic makes it extremly hard for players, because they cant put their hotkeys how the want it. Which is utterly retarded in my opinion. If that would be implemented in the game and lets say people can use WASD as camera move like in FPS-Games and have grenade on F and vehicle reverse on Q it would make it much easier for them to react and to see success in trying and maybe succeeding in retreating a tank without losing all your other units.
And this is why, unfortunately, you have to use programs like AutoHotkey.
My quick two cents.
A lot of people enjoy watching streams over playing because it is a lot less effort for potentially more entertainment to watch a stream versus playing a game like CoH 2.
There are days that I come home from work and don't have the energy to put towards serious practice or 1v1 laddering, but it is still nice to turn on a stream to see what's up.
I could also see it having to do with people being scared to play. Most people are scared to lose so they'd rather sit around on forums or in streams trying to prove themselves superior rather than just playing the game and letting their actions speak.
Basically this.
