I've played about 2 or 3 (I think they were on my stream from a few days ago), but put them away for now until OKW and Brit pop cap bugs get fixed, no point taking easy losses (if there was a way to search against only OST somehow, I'd still queue as them.)
Otherwise, you're right, ideally this game will be balanced for all. Its just incorrect to assume that 4v4 is the priority in balance and that it trickles down which is what some have been arguing here, when 1v1 is and always has been the core of balance with the easiest solutions.
An income scaling solution would probably solve the inherent resourcing issue in 4v4, though I'm not a huge fan of different rules for different game modes.
I'm not either. It could a temporary solution though. Its going to be very difficult to create a singular balance across all game modes, especially when we add new units into the mix quite often (in relation to coh1).
