Cause fuel caches boosting OKW production is not an advantage.
There are many fine 4v4 maps where fuel is contested all game. This does not stop game from proceeding through tech faster and getting into deeper tech options that Allies don't have. Larger maps mean that points on map are harder to contest (I cannot reliably travel 3 minutes with single infantry squad behind lines without being seen). As such resource points stay controlled longer, and decaps are fewer. In some maps there are more resource points, and with more units capping at beginning of game the resources arrive faster.
They aren't. OKW gets reduced income from fuel caches. It's just as much a resource advantage as a Soviet player making them for a USF player or a USF player for Soviets. If both teams make a lot fuel caches OKW will still proportionally be at an income disadvantage.
People say 4v4 maps are to big. I say they aren't big enough! In a 1v1 you need to cover 2 victory points yourself to win. In a 2v2 you cover 1 and so on and so forth. In 4v4 you can have multiple people covering 1 point which gives inherently defensive factions like Ost a big advantage.
If 4v4's/3v3's had 5 points it would spread people out a lot more and mean that you couldn't just sit all your shit on 2 points and win the game. It would force Axis to move around a lot more and let me tell you that moving shit like KT's and JT's around maps IS NOT EASY.
Soviets stock army got buffed, Relic is going to fix USF (soon), and in less than 2 weeks you will have Brits. The issue isn't allied units being shit anymore it's the fact that the factions have gotten better but we are still fucking playing Steppes even though it's been in rotation since
CoH2 Vanilla Beta. Relic has zero excuse for not making an effort towards making better team game maps.
The new maps coming with the Brits for 2v2 and 1v1 are amazing. But the 3v3 and 4v4 maps are just Shittard 2.0 because it's easy as fuck to just mirror a map put a river and bridges in the middle and call it a day.
