Actually the game is the most balanced it has been for many years, with the healthiest commander diversity we've seen in ages, and 3 (maybe 4) factions being viable.
OKW doesn't actually have any counters to blobbing either - if you want to describe it that way. Only Ost has the excellent mg42, everyone else has got to make do.
I refute your statement about healthiest commander diversity.
Right now, yeah a lot of stuff seems to be up in the air because a bunch of stuff may get tossed in a blender and it'll shake things up. That certainly can create an atmosphere where people are trying to come up with new metagames for when the current one is dumpstered with a patch.
But at the same time, one of the significant reasons there's a push for this is because the commander pool is just as stagnant as it has been the entire life of CoH2. Example: Ostheer uses Mobile Defense all the time, which has been deemed irredeemable and it's likely going to be changed. Tournament players weren't even putting in other commanders in their loadout.
We have never achieved healthy commander diversity, and we've never once achieved 5 balanced factions. A 3, maybe 4, balanced faction scenario is where we've been since WFA.
I will freely admit though, that at various times in CoH2's history, there was a mostly balanced, highly enjoyable matchup between two factions: Ostheer and Soviets.
