Heroes expansion, two players one type of hero

[Heroes expansion, two players one type of hero]

 Just bought the Heroes expansion, discovering there are five classes w. respective banners.

So what happens if both players want the same commander? 

Admittedly, this may be a simpleminded question, but does each side have to use a different class of commander? For example, I've got the rogue this game and you've got the wizard? Or do you have to pretend the wizard figure and banner represent the second rogue?

The rules are not clear on this subject, suggesting it doesn't matter and FF just wanted to save money on the figures and banners.

Clarification please.

We're about to launch into this expansion. It seems a rich one and I'm looking forward to it...

Thanks, all.

Man, heavy duty questions...

I think I've got an easy one. But it has caused a minor debate around the table. Here it is.

Inner ring, Dice with Death: You roll, and if you lose you have to dice again. If you win: You May Move Again on Your Next Turn. My stickler buddy cast a Immobility on me, preventing me from moving on my next turn. Then, argued because I missed my window, I had to dice with death on the next turn. We resolved it with a show of hands -- agreeing next turn was any turn in the future, afterall -- death was defeated. But my friend is still not convinced. 

Any thoughts from the commons would be appreciated.
