That explains all.
4v4. Pfff....
I wouldn't complain about balance related to 4v4. Wtf is this game? Counter-strike? battlefield ? The only balance that matters is 1v1 and 2v2. That is the base. The balance is done stating from 1v1 and ending with 2v2. What is beyond CANNOT be balanced and it won't ever be.
That is a poor attitude. 4v4 exists and SHOULD be balanced. Nice comparisons with an FPS....
Why should it end with 2v2?
I like the idea of slowing down tech progression in team games. Right now, medium tanks can be pumped out around 12-15 minutes. Late game basically begins at 20 minutes.
