Tips for OKW in 2v2 and 3v3?

So my friends and I stopped playing right before the OKW overhaul, and we just started playing again. I play OKW and I either play with 1 or 2 wehrmacht depending on the gametype. I am struggling pretty bad with the changes to OKW and was wondering if there was anything I can do to get better. What are the meta commanders and build orders? What works now? Because when I stopped playing, leigs ruled the game. I also have the Goliath commander. What works for OKW now?
