It has a better gun than KV-1, while having double the health, and 10 more armor, and more MG damage even at vet0 (and gaining more at vet1). For 5 fuel and 120mp more.
Yes the Sturmtiger is a bullshit unit that needs a nerf too, but even with the vet2 buff it still has 38 less armor and 160 less health than the vet0 Churchill.
150 fuel isn't 200. Churchill is priced like a medium fuel wise despite having the highest raw survivability of any vehicle in the game.
If comparing with KV1, its obvious that Churchill should have superior armor rather that superior health.
I mean, 152mm of front is more than IS2 so from historical point of view it should have less HP but insane armour, like 1040 (1280 vet 2) with 350-400armour.
But Relic went in different, ahistorical direction, idk why. Still, it has to have great survability by armor or by health.
PS
Did not know they change it to 150
The Sturmtiger at no point ever did larger AoE than the railway artillery piece, the 80cm shell has an AoE radius of 12, the Sturmtiger used to have 10 and now has 8.
Railway damage at radius 4.5: 0.15*600 = 90
Railway damage at radius 6: 0.05*600 = 30
Sturmtiger damage at radius 5: 1*640 = 640
Sturmtiger damage at radius 10: 0.3*640 = 192
