At first that Aetherflow macro is fine, but you'll want more control later, so axe it. Pressing too quickly can cause line skips and activate Aetherflow instead of energy drain. I did the same thing.

Dissipation is a god send, you just have to learn to love it's bitter flexibility. Don't forget you can add an extended hotbar. For flexibilities sake I have it set to the same hotbar, so only 8 slots.

I divided mine up into 5 hotbars.

1) Eos DPS
2) Eos Heal
3) Selene DPS
4) Selene Heal
5) Rarely used skills/ Extended

You'll also want to interchange Stoneskin and Blizzard II, depending on the content.
