Not really, I have been a big user of Armor commander since months now and M10 has been nerfed as well = +1CP and 10 fuel increase.
The Armor commander efficiency has decrease with the OKW resource buff, it is simply mathematics:
You need 2 M10s to counter 1 OKW P4 or P5. Before the buff, you barely see more than one of those together in a game. Now OKW can field really fast 2 P4 or 1 P4 and 1 P5, if he is not stupid he will simply stale a bit with them. You finally finish not having enough firepower on your M10s to counter them, and when he lost one, he'll replace it with a KT.
P4 had a price increase as well which you dont mention. not surprisingly, looking at your playercard.
my suggestion is you abuse the hell out of the OKW-OPness as you describe (and with that i mean playing more than your 3 OKW 1v1 games) and when you cracked top 100 which should be a walk in the park with OKW according to you, you post again
