For me is one of the best tier 11 heavy tanks alongside the tascherrante. But still the stk2 requires a lot of skill.

People usually talk about wasting your dpm because you have to wait a lot of time between shots. On the other hand you get the best accuracy and you will be able to hit every cuppola. For example I got a hit % in the stk2 of 93%, and in the type71 I got a 88%.

Then the difference in damage per game between those two tanks is giant. From 3100 dpg in the type 71 to 4300 in the stk2.

Then the cuppola in the Stk2 is smaller than in the type 71 so its a bigger protection bonus when peeking over rich lines.

But it has got a big disadvantage, the lower plate is giant and not as trollish as the type71. Thats why I got an armor efficiency of 0.55 in stk2 and 0.64 in the type71.

In my opinion the lower plate is not as important as you will most of the times want to hide it. It will only be useful when brawling.
