My concern is this, the 88mm L71 will command large amounts of space given how open AH terrain usually is, making circling around to the flanks and rear of the Tiger II difficult to say the least. I am not sure the three free tanks, Panzer IV H, T-34/76 and M4A3(75), will be able to defeat its armor from the front at any range, even with the decent 75mm on the Panzer IV H or the T-34/76's HVAP rounds. That being the case, should a Tiger II be on the field against opponents who, for whatever reason, have no vehicle perks to buy, and likely lose, a lot of T-34/85s it may prove to be, effectively, an immovable object for those three free tanks.
Yes, there are still 1000lb bomb lugging aircraft to use on it, but it seems kind of a shame to, potentially, push people in a tank fight into aircraft to deal an opposing tank.
