This is a very bold claim that I actually disagree with.
But instead of just saying that it made no difference, can you back it up with some numbers?
i think what hes saying is having a little bit of extra armour on 1 tank over another doesn't make much difference ingame as the chance to pen only changes a little bit, so small its really insignificant. Ther are more important values that make more of a difference like health, accuracy etc.
Look at the panther, it had its armour nerfed and vet 0 health increased and it was a considered a survivability buff for the panther. People need to stop with this myth that allied tanks don't have well armoured tanks. One other reason as to why heavily armoured tanks on allies makes so much more of a difference when on axis, is because axis simply dont have 60 range high pen TD's so they tend to struggle more vs tanks like churchills compared to when allies have to go VS a KT.
And srsly OP, REKETEN IS THE WORST AT GUN IN THE GAME AND MAN WANTS TO NERF IT. srsly OP list for me in order which u think is the best to worst AT gun : (6 pounder, reken, USF m1, PAK, and zis)
