If blaster secondaries are being looked at, and quality of life changes are being included, I have some requests, if its not too late to introduce more changes.
Martial Combat / Reaction Time
Make the animation interruptible, and maybe also reduce the animation time.
The quirk of deactivating your absorb and recovery to get a short speed benefit is not practical to experiment with, even out of combat, because the activation animation forces you to stop to reapply it. If it could be done without interrupting movement at least, or even without interrupting your attacks so much, so the only costs are the actual temporary loss of absorb and recovery, and the attention needed to be given to press the buttons, it might fulfil the aim of the design.
Devices / Field Operative
Make it possible to have the recovery benefits applied without the stealth fade visual effect.
This could be accomplished with a 'no fade' power customisation option. Or it could be a splitting of the power into an auto power with the recovery effects that also grants an unenhancable 'cloaking device' stealth toggle.
It sucks that if you want to make a blaster themed around technology or weaponry, your character costume has to be hidden in combat, even if this doesn't fit your theme or if you want to admire your character's combat animations, because you can't afford to skip the recovery effects added to this power. This power only became a must-have when the blaster recovery buffs were added to existing powers, which I think was only a recent change (relative to the game's history).
