Fair enough, but that raises another point. Given the name "Panzer Elite", there aren't an awful lot of Panzers available.
If PE artillery is to be limited to Scorched Earth only (which is fair imho), then perhaps the option of replacing 2 heavy howitzers with 3 light howitzers. More options means more creative strategy evolutions.
Jagd[tiger] is a buildable replacement for the Kettenkrad... It can cloak and cap points.
Would it be possible to have the choice (as a reward unit, perhaps) to replace the Panther Battlegroup with something more along the lines of panzer support rather than actual frontline tanks. At first I was thinking 3 Pazer IV's for roughly the same cost, but what about a battlegroup of 3 Wespe SPG's? The Panzer Elite are supposed to be the elite, implying better access to funky toys like the Funkwagen and Kettenkrad.The Wespe also fits with the high mobility of all PE doctrines...
