0.5 x 40 = 20 not 15.
How much time do you think that 4 T-70 need to fire 8 rounds?
Point here is that deflection damage promotes spamming vehicles while making Super heavies unable to cope. Already 3 SU-76 can take out an Elephant without any deflection damage, try to imagine what would happen if deflection damage was added.
Both the accuracy mechanisms and armor mechanism are good mechanisms that add dept to combat. People who do not like them should probably stick to AOE or other titles that do not have RNG elements.
Yeah 20, my bad. In any case t70 I belive have around 2.3 or so ROF, meaning that it needs around 10 seconds, to deal 160 damage.
And honestly I dont think that horde of T70 should be able to kill KT. Like lets be real here, the only and single possible scenario when it might happen if KT is completly unsupported, but thats my imo.
Anyway deflection values and chances in vCoH werent universal and were specific for for pretty much any projectile, so such situations\units could have been ajusted to fit the game better.
As for spamming, the fact that game only has only hit\miss and pen\non-pen AT hits only promotes spamming high penetration units and massing AT guns or having TDs in the game balanced around solely the idea that they pottentually will be fighing heavy tanks, therefore they need godlike penetration values making them no-brainer against all types of armor. Honestly dont know what is worst.
Fact is in vCoH it worked, KT was a godlike tank in vCoH and only few units had cappabilities of actually penetrating it frontally, but since deflection damage existed it allowed your AT units to keep at least some value against it by dealing cheap damage to it. If it was CoH2, then pretty much all your AT units would have become obsolete the second vCoH like KT hits the field.
