I play on console. What gets me is the number of nothing-special premium tanks. Bad players buy $50 tanks and get wrecked by lower tier tanks.
There are several that I view as pinatas for me to beat on for XP when spotted. I salivate when I spot a Tog II, especially in something like my Chaffee light.
Also, several times a year you can earn premium tanks. I earned both the Fatherland and Motherland Tier 8's and swap the crews between my top tier russian tanks and those two to build their xp.
OK, you're a more serious WoT player than I am, my top tanks are a couple of Tier 7s. But I agree about the Tog II . . . it's so slow, when you catch one without allies, an LT can just keep circling faster than the TOG's hull and turret can traverse - you just keep hammering it with relative impunity.
But sometimes, hammering doesn't work. Once I had one of the light Brit tanks and came up against a KV-2 opponent, which was 2 tiers higher than what I had. I absolutely could not pen it from any direction - front, back, sides, turret, hull, and tracks were completely immune to my little popgun.
Then when I got my first tank with an 88mm L/56 gun (a far cry from the L/71 to be sure) I bounced 21 consecutive shots off 4 or 5 different opponents in one game. And by then - casual player or not - I knew enough not to try penning the front glacis or gun mantle, especially of higher tiers. The problem was, I couldn't pen the sides of either hull or turret of ANYTHING on the other side that day. That's when I began seriously doubting WoT's implementation of RNG.
