This update brings some interesting stuff. Sadly, most of it is bad. I left a nice long comment that hasn't been approved yet, but here it is.
In short, this is basically what I'm suggesting for the BRs we see in Tier 6 for the MBTs alone, and in their current form:
8.0 - Chieftain Mk 3, Chieftain Mk 5, AMX-30B2, M60A1 AOS, STB-1
8.3 - M60A1 RISE P, Type 74, T-55A, AMX-30B2 BRENUS,
8.7 - T-62, Leopard A1A1
9.0 - Chieftain Mk 10, T-64A, XM-1s, XM-803, MBT-70, KPz-70
9.3 - T-62M1, Challenger 1, AMX-40
9.7 - 2K, T-64B(V)
10.0 - Type 90, M1 Abrams, 2A4
