The planned battle level changes did not improve the situation at both low and high levels

Dear Gaijin team,
There seems to be some problems involving the upcoming BR adjustment.
First of all, I would like to admit that you’ve done a good job balancing out the vehicles among BR 7.0-9.0.
However, the problems occurs at the BRs ranging from the current 9.3/9.7 (which will be 9.7 and 10.0 later). Which in brief, moving the vehicles of 9.3/9.7 up without moving those of 10.0/10.3 will cause a compression of the unbalanced matchmaking. There is already a significant performance gap between vehicles of BR9.3 and 10.3. See the problem is without further extending the BRs of those whom already is 10.3 or higher, the vehicles of lower BR will experience a way difficult time after the BR adjustment. Moving only those of 9.3 and 9.7 up will only make the situation worse.
Luckily, I do think there is an easy way to solve this. By extending the maximum ground vehicle BRs to 12.0 or higher, the vehicles currently rating 9.3 and 10.7 will still be separated in different match makings. Also, moving vehicles of 10.0 to 10.3 and those of 10.7 to 11.3 (since most of them seems to be over powered that they need to be ranked up by 2 tiers) might also be helpful to the matchmaking environment including game balancing.
Same story happens to the vehicles with BR6.7/7.0. I know it is hard to balance out the vehicles, but there needs to be some adjustments to the BRs of those vehicles and I have great confidence with the gaijin team.
Thank you in advance,

a couple of the 11.3 and 10.7s are op but stuff like the ariete shouldnt move up as they are already incredibly overtiered
