I think some of the asymmetry in the current game is ok, though its hit or miss and the devil is in the details.
I like Grain Elevator. Yes, when you're new, you will get spawn killed until you learn where to take cover. It can get repetitive if your team coordinates badly and puts you in a stalemate (just like any other RO2 map). However, I personally enjoy the challenge of playing German on the map, knowing that the chips are stacked against me... I sort of like getting revenge on the Russians for my prior deaths on the map.
By contrast, I hate Apartments. That's a map that feels too asymmetrical to me. It's way too constricted, there aren't enough options to outsmart the team that has you pinned down...as the Russians, it tends to just be a matter of running out and getting mowed down over and over till the enemy slips up.
That being said, I always find it interesting when I play the defending side on these asymmetrical maps, that it's not as easy as it looks. You might assume it's going to be turkey shoot, but if your team gets lazy, you can get overrun pretty fast.
I would rather see more of this type of balance-through-map design, as long as it's done well, than artificial weapon balancing via the sort of recoil boosts and prototype additions we saw in RO2.
