Vipper is trying to defend how a buff that gives 10% free hp to already durable tanks (with 960 hp non doc and well over 1k hp on doctrinal heavy tanks) that ALSO applies on allies is balanced because the p4 isnt like the okw command panther and cant fight it's own battles. Some of the doctrines also include spotting scopes and/or panzer tactician, so you know, must need a buff
Personally it should be like a standard wehrmacht panzer 4 F2 so it can not only make elefants, tigers or massed panthers even tankier, but also apply the buff on itself and kill your hopes and dreams in team mode
why is your axis winrate at like 40% if they are so OPOPOP like you state in every post of yours
