The 2.2 patch will be improving Lightwell (or LOLwell). Lightwell will benefit from 100% of + heal. Allegedly, it will also place a debuff on players that are receiving the healing benefit from Lightwell so that one player cannot use all of the charges, though this is currently not working on the PTR. So, given these improvements, will you spec into Lightwell? Personally, I think Lightwell still needs something more in order to make me give up a point for it. Perhaps no break on damage, though there has been talk that this would make it overpowered. Another option would be for Lightwell to regenerate mana as well as health. This option would definately cause me to give Lightwell a second look.
