With the amount of viable strats the soviets have at their disposal I think some of the accusations of boring meta are down to players not experimenting enough.
This. I have to strongly disagree with people who claim that the boring meta is due to balance.
I haven't seen anyone in many months try to go for multiple MGs as Germans for example. I do it a lot and it works very well, but you have to change your habits a little to make it work, play the map differently.
It's been only a month or so since the patch came out, so I don't think we've figured everything out.
