Preliminary stats for update 7.4 have been added.
In general it is great to see Tech Tree tanks taking three spots out of the TOP 5 best performing tanks. The Relative WR figures tend to be bit lower for the new tank lines since many people have been grinding the tank with stock crews and modules. It is not uncommon to see Tech Tree tanks improving their performance stats 1-2 updates since the release. This is despite the fact that I filter out players with too few cumulative battles in a Tech Tree tank to avoid including too many stock tanks in the performance stats.
