Admiral Chiraneau
Squadrons that you activate can move even if they are engaged. When an engaged squadron moves in this way, treat it as having a printed speed of 2.
Corruptor
The speed of each squadron with BOMBER you activate is increased by 1 until the end of its activation.
From the new FAQ:
Q: Do effects that change a squadron’s speed value also apply when the squadron moves because of a card effect?
A: No. A squadron’s speed only applies when it performs its standard move during its activation.
Please correct me If I'm wrong. Before the latest FAQ, it was unambigious. Engaged bombers activated by the Corruptor with Admiral Chiraneau could move away from the enemy fighters engaging them; and at speed 3.
Now with the new FAQ, it has become a little more iffy. On the one hand, the Corruptor-Chiraneau combo applies in the normal squadron activation, which would mean that speed 3 is still possible. On the other hand, the bombers only move because of the card effect when engaged. Without the card effect, they couldn't move. And because the "effects that change a squadron’s speed value [...] apply when the squadron moves because of a card effect" the speed is now 2 and can't be changed by Corruptor.
How do you see it?
