According to WOT Express, it looks like the upcoming 1.27.1 update will include buffs for the Japanese Type 71, American M-V-Y, and the rest of the tanks to the top-tier vehicles.
“And this branch of tanks headed by tier 10 is already in the next update! This BUFF has been expected for a long time. On the TOP, you can just choose the New Year’s discount. But whether it will become meta – time will tell.
The total for the next patch is already known: 1 nerf(60TP) and 2 Buffs(Type 71, M-V-Y) .”
I never saw a real need to pick up the boring seeming japanese gun cooling heavies, but now im looking forward to them. As for the Yoh tanks, they obviously seem to struggle from what ive seen and played so im glad they are getting something.
