Haha, I loved your reaction to the Sturmfusiliers. Those guys are brutal, and should totally not come with the Wespe. I still want to see them in the game, but by god, they are way too brutal the current way they come in. You did good against Simus though!
IMO there is no need to have two different call-ins, specially if the Wespe is better than the Panzer 38t which I only see like an "oh shit!" call-in but weaker than the other "oh shit!" call-ins. But I guess we could wait for the patch being released and tested by everyone to get more feedback.
