I think it's very good - it just may not be ideal for your build. If you have a lot of skills to choose from, it may not be worth using, however, if you have a few important skills with long cooldowns - it can be a good way to end a fight. Personally I use it on my wayfarer (I guess that would be the closest class - archer/buffer/healer) to be able to unload buffs, heals, and chameleon/snipe then for 0 AP, refresh all those important skills and use them again next turn. I could also see it being useful (though potentially dangerous) on a warfare build to refresh all knockdowns in a pinch which basically could keep multiple enemies CCed for multiple turns (if you rotate knockdowns). It may be situational, but the fact that it costs 0 AP puts it close to the "overtuned" side of the power spectrum.
