Changing the BR Grid in SQB

When are changes to the BR planned for the second week of SQB? Since it’s been the same 12.0 for seven seasons in a row, I’d like to see 12.3 or 12.7, because the same tactics are used over and over again at 12.0 and nothing ever changes. Maybe instead of 12.0, I’d like to see a change to 11.7.
We need this change because for the last seven seasons, the same equipment has been used consistently in the second week—specifically, the Gripen and Pantsir alongside the Abrams tanks—and that’s it; there’s nothing else. Well, there are also the same helicopters: the Ka-52 and Z-10.
