Despite the bad turret and gun handling of the t54 it has actual working armor that not a lot of tanks at that br have, they have really good ammo (though in case of the is2 the reload is the biggest hindrance and imo the point where the snail could actually buff it a bit because bumrushing in , flanking and getting multiple kills as fast as possible is meta nowadays)
And what most people seem to forget a remote controlled 12.7 mm dhska with great traverse speed that can almost shoot straight upwards and uses incendiary shells with every round meaning that a lot of times one hit sets an enemy plane on fire while the tank itself survives a 500 kg planted a couple of m next to it regularly
T-54s don’t really have working armor against most main cannon rounds at their BR. They traded everything for that and it isn’t even that good to begin with.
IS-2 is locked in a single playstyle due to horrible reload speed, gun handling and gun depression. It’s egregious that it’s still at 6.7.
i mean yeah obviously the kingtiger has much bigger potential for high kill games, but i wouldnt go so far as saying the is2 is bad at 6.7. Could it go lower? most likely, but on the other hand on 6.3 we already have the 76 Jumbo and what do you do with that when you face it in a frontal engagement in the IS2 and it can do nothing to you but try to get your gun? Thats right you just lolpen it through the ufp. and thats a 0.3 difference in br between heavy tanks while ur facing tanks from 1.0 br difference higher or lower. Snail does what snail wants.
Vehicles like that just have little to no place in the current game. Their crippling flaws outright stop them from doing certain things, which promotes the same old boring gameplay.
6.3 IS-2 can do it already.
Jumbo also have an easier time to kill an IS-2 than a Tiger II H.
