HOWEVER
That doesn't mean OKW isn't too strong right now, the main issue hereby is the popcap that snowballs too strong in team games.
When armies are maxed out, OKW will have a massive advantage, due the fact they can have more units with their 100 popcap, so you will face more troops than you can field as an allie against OKW. Especially when you see how absurd some popcap is, shocks being 12 popcap, bolstered sections being 10, while Obers are 8 (just like Grens

It also means a massive advantage over the course of the whole game, as the lower you popcap is the higher your MP income is. You can easily afford all massive MP investments and never really have to save up for it, all other factions have to carefully think which upgrade and which units they have to buy in order to keep a good MP economy over the whole game.
This whole popcap issue deserves a hotfix. Right now it gives and massive advantage and overshines issues that might come from units cost wise & teching wise.
