"You cannot use this action to do something you could not normally do (e.g. make a Charge action with a fighter that has already made a Move action in this phase)."
Well, but normally you can take any action when a card tells you that you can take an action, so "normally" would be "normally as written in the rulebook"... ;D Question: is there anything in the rules that makes a move/charge actio after move/charge action treated differently than attack after a charge?
Maybe at some point we'll get a clear FAQ, who knows :P.
