OP i really don't understand why you are complaining so much about the T-34-85M when its your tier VI medium with better average damage...

Its also one of the best tier VI you have measuring the WN8 calculations...
So i really don't get it, you sell a reward/premium vehicle because of amoracks? perhaps you should pay more attention to details, the T-34-85M is pretty much mandatory for tier VI clan war's, and that's not just because its Russian...
It's better armored than some tier V's heavies, it have very good dpm for tier VI's, the alpha is also fairly good for tier VI medium, when you are top tier, if you are a competent player there is a very high chance that you may dominate the match if you know how to play it and how to win...
That said, its stupid to sell premiums, you don't need dedicated crews for it...
WG gave me several lower tier premiums which i am not particularly fancy off, but, they are still in my garage, you never know when you will need a lower tier tank to platoon party or just for seal clubbing.. .
it doesn't make sense to sell them, you are going to regret it....sooner or later you will regret it.
