You have purposely made the challenges to make your most toxic tanks the most played. Tanks like the mk1/xm800, atgm tanks like ignis, t55, auto guns of all kinds.
Although Era 3 isn't nearly as bad, this contract shows just how bad you have made Era 2 into. You have completely lost site of balanced gameplay and continue to support those toxic game ruining tanks. I'm not sure why you are doing this while saying "You are listening"and care about player experience.
Then with your upcoming changes you aren't doing anything to fix these issue. If anything it will make alot of those tanks more toxic. I love this game and its sad to play and feel how cheap the gameplay is now. I hope you can understand and actually care about player experience and stop supporting your most toxic tanks.
Also just to add these tanks in thier own aren't that much of a problem however when you support this many being played at once. It really makes the gameplay feel cheap and meaningless. Atleast to me.
