Good day, i got this hypothetical idea..
Would it be viable to have a cancel aura macro moonfire to cancel lunar shower, so that you can multi dot aoe targets while still not going out of an eclipse? This way you could you use your normal moonfire during movement to get into your desired eclipse after movement.
As i said this is only hypothetical but do you think it would work?
You are a bit too late on this matter :P
Blizzard hotfixed it soon after Patch 4.2. You cannot remove the LS buff.
Just don't spec into it. It is clearly a PvP talent in it's current form and a dps loss in PvE.
