So yesterday I finally recruited Starlight and Queen Maeve and as I was figuring out who I was going to fire to make a slot for them it struck me that it would be cool if these special multi-skill commanders could be switched between tanks without re-training. A "premium" commander, as it were. Like premium tanks, only backwards: said commander can be used on any tank of the nation without retraining.
Anyways, you've probably heard this before, but I for one would like it.
