SG could also be misinterpreting the data and simply counting wins with a certain tank regardless of the team behind the tank. For example, putting 3 Gravemakers behind any tank would skew that tank’s win rate higher.
Just sayin’… could you record your revenge?
And in all seriousness there is a huge selection bias here. People underestimate unpopular tanks and are more likely to hit them and then lose. I’m taking advantage of this in my cup dropping team.
