I think the Sturmtiger is incredibly powerful and I have loved using it since day 1 of WFA. But the fact of the matter is Elite Armored is a very buggy commander.
Elite armor is not at all bad,its rather pretty good when u know how to play with it.
ST fits perfectly in that doctrine :
1)Detection for ST or other vehicles to hunt or kill already damaged tanks.To know which unit u are seeing u have to use tac map btw.
2)crit repair for mine or naded flak/puma whatever.
3)Heat increases dmg and pen,imo better than mark vehicle.
4)Panzer commander always useful for vet p4 or Panther
5)Already known
That doc heavily relies on vehicle play and preservation if you play differently yeah then its only good for ST.
I even uploaded a replay against a rank 150 soviet "armored assault" guy on semoski which is definitely not the best map for it.
