There is a point, spall, more pen = more spall.
More spall = more damage
More damage means you kill enemy better which means you don’t have to aim as accurately compared to lower pen rounds for pure damage.
Better pen also means weakpoints are larger
The importance of armour, translates quite well into WT, actually armour is less important in wt, ESPECIALLY because it’s a video game.
Aiming for weak points is significantly easier and things like your awareness are significantly better too. In WT we also carry much more Anti-Tank munition than you would IRL.
This all makes armour much less effective than it would irl.
I wouldn’t exactly call the T-80BVM an okish tank with its mobility and the reload is just fine when using 3BM60. The armor is good frontally and ofc not really the case side on because barely any tanks can say they have good side armor.
And yet the mobility of it remains good because acceleration is really good on the thing, the reload may have the 6.4 seconds but remains consistent no matter what due to it being an autoloader. While once the loader in every NATO MBT (Except the Leclercs) dips.
Yet, because it’s an autoloader, you can’t reload the moment it’s damaged and your reload is consistent, meaning everyone knows exactly how long your reload is and whether they beat you or not
Its more aggro, but once you’re caught out you’re out of options, western MBTs can retreat to cover instead. Much more preferable than having to rely on how well the enemy can aim
And? I could say the exact same thing with NATO tanks now that more of them have a turret basket leading to moments where they can shoot out the autoloader but you shoot out their turret basket
