I think we missunderstand each other. Balancing is one thing, approach to meta / counters / etc is something else, and perceived balance another part.
As i said before: the counter has to be more intuitive and approachable. There's no point in over- / under-buffing by public demands.
There's no such thing as a plain Top200 in COH2 to begin with. 22 ladders of 200 players is more like it. Relics Alphas usually seem to consist of mainly Top1000 players from all modes (with lots of strays from lower ranks), so there's that. I'm also quite certain Relic is aware of these statistics.
IMO, you have to start the balance in RTS top down mainly due players experience. A top RTS player will see certain meta way before it becomes common. They're also the ones that can break the whole game by perfecting certain strategies.
But, sure, there has to be another step, meaning "is this feature intuitive, approachable, and not too frustrating for the larger crowd".
Your "balance" is just a lack of intuitive and approachable counters, with screwed up MM.
And another
but: apropo MM, as i said a hundred times now, even a perfectly balanced COH2 will have lots of perceived imbalance if MM isn't on par - and that's one of the main reasons why the 3v3 / 4v4 random stats look so weird.
There were even plenty of posts claiming Ostheer is super OP now in random 2v2, just because their win ratio was very high for two days - plenty of Top players said "nope, it's quite fine", and guess how it looks like today?
So, i would look at these statistics very carefully, not interpret too much into them regarding actual balance, and instead ask for reasons why people think certain units are not approachable for them.
Sadly the forums are full of topics and replies claiming xyz has to be "downright OP", instead of "this unit is not very practical to use for me", or "why the fuck do i constantly face people way above my skill level".
Well, hope you get my point.
