Lightwell has been meme for far too long!
update the CD from 10 minutes to like 1 minute and remove this part from the spell already.
Being attacked cancels the effect
Holy shock, lets get inspired by the stormstrike where CD has been reduced to 6 sec. Let it be on the 10sec cd max, the healing would be still weak, but at least viable. We dont have to worry about the dmg component as it is equal to 1 tick of void plague from SP.
Beast mastery rune has been succesfully nerfed so, there is no reason to keep this on 1min CD. Reduce it to max like 15 sec.
Updates to moonkin form, shadow form, stormstrike are great, but other specs should have fun as well.
