Seriously.
If you are still having power issues when soloing, these are the answer. Thanks to them, I've been able to ditch the separate set of +Will/Power gear I had to carry around for grinding skirmishes and dailies. Now I go straight Might for maximum heart-ripping efficiency.
The OCPR really makes a huge difference. Munching 2-3 non-crit rations over the course of a skirmish allows me to blow through it in Recklessness (with an unranked soldier...) without running out of power or waiting to regen. Even the non-crit version lasts for 5 minutes and refills your power bar out of combat almost instantly. Skirmish fights are short enough that ~1K ICPR and starting every pull with a full power bar is plenty.
Another lovely thing is that you don't even notice those annoying -Will/Fate fear debuffs that some skirmish mobs spam.
