Didn't think of macros when creating that ability, although 5 per second is too low cap I think, as Energy Shot is meant to be a pure DPS ability, but with 5/s it is out DPSed by Twin Fang (100 +40% AP vs 380 +110% AP in the right conditions). Having it a toggle would also make it weird and possibly fire at unwanted targets too much.

Mana regen passive sounds good considering her main ability, I'll see if I can find a nice one.
