I know in the past prior to Wave 2 there was much discussion on using Mithel and Chiraneau and the FACT that you could use Chiraneau to move Mithel and only MOVE Mithel "0" or say a millimeter then cause 1 damage to enemy squadrons that you were already engaged with previously.
So what about using Mithel with Dengar? i see no reason why , based on current ruling (unless FFG FAQs it), that you can't fly in Dengar to place HEAVY on squadrons already engaged by Mithel and then use Mithel to move "0" or a millimeter because of HEAVY and deal 1 damage to all squadrons Mithel is engaged with?
