Im not a expert on WW2 weapons so i dont know for sure if panzerfausts were as accurate as they are in ET. Anyways, i propose that add "jitter" to the accuracy of the panzer would be great. Since atm its as accurate as a the covop sniper thingy.
Panzers are best at mid-short range, it's harder to get long range panzer kills since it moves so slow.
Maybe it should load the next rocket into the panzer before you can switch weapons...
