Being Staggered/knocked Down Should Not Affect The Interface

[_Kireek_]

Somethin's been bugging me. I use a controller (yeah, sue me) and so instead of having a button for each power, I have a Next Power, Previous Power and Use Power. Obviously, I shouldn't be able to use powers while knocked down, but why the heck can't I change the selected power? When I'm meleeing away and get mobbed, and someone knocks me over, my instinct is to change to Crush while I'm getting up so I can use it as soon as possible. But in the second or so it takes me to change power AFTER getting up, my shield is broken, or I just get knocked down again (especially in mobs of Chargers, ugh).

 

tl;dr Please let me change powers even while my other actions are restricted.
