The 279 has the hp/t of a medium and the reload of a medium. It also has the benefit of being able to potentially bounce rounds in a BR where almost everything OHK. Thats you ardvantage. Or did you think that heavies should have almost every advantage over mediums?
If i’m in 8.7 i shouldn’t be nearl invulnerable to -1BR. NO OTHER TANK is. Every KE shell of 7.7 cannot pen the 279 and many CE shells are still 300 pen.
The only tanks that can’t pen the Tiger H1 in a full downteir are churchills. Try again. Even then, the APHE of the NA-75 can pen the cupola and kill half the turret crew.
The KV220 is a russian premium that turns out, is also a problem. Literally another thread about the 220 on the front page. Probably a bad argument for you.
The maus is 20kph and a glacial turret rotation. Again, if you are going to get good protection, you need to have detractors that balance you out. The 279 has the opposite, with DOUBLE the reload speed of any historical document can turn under movement THREE TIMES faster than the T95E1 medium tank. Its an utterly fantasy model for the tank.
Chieftan is the best comparable tank to the 279 at 8.7 and 9.0. It has a similar weight, but far less HP/T compared to the 279 while both are armor dependant. Again, the 279 wins in nearly every category, often by large margins.
Tiger 2 vs 76mm sherman is literally what 6.7 has been since the beta. Tiger 2s have proven far less than the unkillable target you present. Turns out, being heavy, poor track traverse, loud, and having a flat turret face thats defeatable by the weakest APHE are weaknesses. Which, again, the 279 doesn’t have.
Look at the pen map of the french 120mm vs the 279 if you really think you have an argument. Then remember that the Loraine and AMX 50-105s are also 7.7 with worse guns. Or how about the 84mm on brit tanks. Maybe you think that the 120mm 480 pen Conqueror has a chance? Nope, pretty much nothing except a tiny ridge under the turret at point blank that nearly never OHKs on a 18s reload rate.
