BD #002 - Firestorm

[Quebbster]

:star:FIGHT FOR CONTROL: At the beginning of your turn, if Firestorm has no action tokens , you may roll 1d6. If you roll 1-3, Firestorm can use Penetrating/Psychic Blast. If you roll 4-6, Firestorm can use Perplex. He can use that power until he begins your turn with no action tokens.

:g-starburst: RESTRUCTURE: Give Firestorm a power action. You may destroy up to three wall segments and/or blocking terrain within his line of fire.

Can I choose not to roll for Fight for control if I want to keep the power I currently have?
The roll itself is optional, but the power you gain is lost as soon as Firestorm begins his turn with no tokens. In other words, there is no benefit to not rolling as you won't get to keep the power anyway.

When using Restructure, are the wall segments or blocking terrain destroyed all at once or one at a time?
Since the power does not explicitly say they are destroyed one at a time (like Crisis Speedy or AA Element Lad), they are all destroyed simultaneously and Firestorm needs to be able to draw Line of Fire at the beginning of the action to all terrain he wants to affect.
