I wish that Energy Drain got an updated spell effect, it doesn't look like it fits with the new dps abilities.
Some people might not care ( or they just want to handwave others opinions away, because dear lawd forbid that people have opinions ), but Energy Drain isn't all that exciting to me as it is.
If I press a button I want to notice it and see it on the screen, I kinda almost don't with Energy Drain :P.
