Avre was mentioned various times in this thread beeing similar in wiping quality to ST, just not by op. Even its turret was mentioned as an advantage to be more responsive and to aim faster(->MMX). So your claims hold little water, various people pointed out that the Avre should be handled the same. Just stop your "biased" call-outs, the forum is able to talk about both sides. Its just your perception.
This turret is not an advantage and a good player disables auto-attack so that the tank does not rotate the turret, because the turn of the turret is several times slower than the turn of the entire hull of the tank.
Secondly, I still do not understand why everyone forgets that the assault tiger appearing at 8 CP very quickly fills the veteran level, which allows him to attack anything, even if two destroyer tanks shoot at him - he will arrive, take a shot and leave without losing and half of the hitpoints. And it can still be kept on the battlefield with KT.
I guess it is not such a big problem in 1v1 and the balance team plays mostly in 1v1 and 2v2, but in 4v4 there are matches against 4x Sturtigers and this is not normal. 4 OKW players can have 8 call-in heavy tanks.
