Tiger I as a Tier 6

Lert:   Please explain how an 88 L/56 at tierb6 on a Tiger has more penetration than an 88 L/56 at tier 6 on a VK36.01H.   @OP: your idea would leave us with a tank at tier 6 which has very much the same mobility as VK36.01H, the same armor as VK36.01H and the same firepower as VK36.01H. We already have a heavy  tank at tier 6 with those atttributes: the VK36.01H. Tiger as it is now at tier 7 is a very, very powerful tank in its own right. Don't stare yourself blind on the historical reputation of the tank, that's a result of it going up against what basically amounts to stock tier 5's.
