Aetherflow Combat only?

What is the point to making this "Can only be executed while in combat" only?

This skill can only be used for healing now. When I walk around jump off things or see some one in need I pop my Aetherflow and use Lustrate as a quick fix up.

The skill has a 60 second cool down and has no buffing effect. Having Aetherflow bar before a fight is no different then having full mana before a fight... Lustrate is pointless untill damage has been done... Same with every other skill that uses Aetherflow.... They all are pretty useless till the battle gets heated.

All this has done is made it harder to help random people out in the wild... Oh and made me stay half dead a little longer after a fall.

To the best of our guesses, it was to stop pre-pull waiting for Aetherflow to recharge...As if any SCH didn't already have that prepped before going in?
