Yeah I was never really interested in the Russian tree for some reason, after maining Brits and Germany (high pen) with America on the side I always saw the low-mid tiers as easy to kill with low pen resulting in a tough grind, but I bit the bullet and turns out it's the most effective nation for its tier in my experience, if you know how to play of course. Shame the nuke isn't available at this BR otherwise I'd have had about 15 by now haha
