I'm really confused now as to which faction is currently considered OP. I mean the steamroll argument with allies is pretty good, but so is the hold-out-until-armor-arrives-for-axis one.
We really need more search percentages statistics to determine exactly which faction gives more reason to complain about.
Thats because the "balance" of the game right now is OP Allies for the first 15 mins - then OP Axis the remainder of the game.
In Relic's eyes - that's "Balance".
Hence depending on your game variant you play - in larger team games (2v2 or greater) the longer the Axis can hold out and the more OP they become.
