It's impossible to satisfy everyone, but a decision still has to be made regarding the T-34. I feel that it fits well where it is, despite how it may have been in history.
Pripyat does demonstrate the issue, but my argument is that it isn't a good idea to balance a concept based on an outlier. The competitive community will prefer maps like Kholodny, Oka, or Moscow, all of which have plenty of ways to flank your enemy and maneuver vehicles. Side armor should be balanced based on which maps will be used the most, rather than what maps are special cases. Trying to balance side armor using a map like Pripyat will cause imbalance issues on other, currently more balanced maps.
You should be forced to sacrifice a T-34 against a Tiger either way. You can either ram the Tiger, destroying the main gun and crippling the engines so that it can't get away and can't cause damage, or watch as the Tiger destroys one of the T-34s. I think it'd be unreasonable if you were able to keep all of your T-34s alive against a Tiger, especially considering the cost difference.
Regardless, Pripyat is the only map that makes it difficult to flank a tank. All of the other maps in the closed beta allow for easy flanking.
I wasn't suggesting I shouldn't have lost a single T-34, I was just amazed by the amount endurance the Tiger demonstrated.
Concerning Pripyat, I agree overall, but like I said, this map greatly allows a player to potentially exploit the lack of side armour. It's still a map which will be played, which means it is a map which will show the problems of not possessing side armour.
I disagree with the mentality, of "ah it doesn't work with this content, so I'm going to work around this content". It can potentially promote, and excuse bad-game design.
It necessarily doesn't need to be at a choke point either, it's entirely possible one could do it with a building, I assume.
It wasn't to say the mechanic doesn't work in one map, it was just to emphasize how this could potentially be abused.
We haven't seen all the maps, so I will reserve judgement, but in the end, it can lead to gaining a huge, unfair advantage.
