Tiger doesnt need Blitzkrieg, really. The surviveability of some German Tanks is slightly too high, especially from Panther
Especially from Panther?? You ever used a Panther ever? Unless you get lucky with RNG and lots of shots bouncing, 2 T34/76s will rape Panther.
How about IS2? That thing has much more armor than Tiger, is faster and has a better gun, yet costs the same. Only thing Tiger has over IS2 is blitz and reload time and I guess it's a smaller target, but none of those things make up for the other differences.
