Why does HR has only 10y range? PoH is 30y, Wild Growth 30y.
HR 10y
LoD 15y
Holy Prism 15y
LoD with 15y is "OK", could be larger, but HR is just so bad unless the raid is standing completly together (Gara'jal). But for fights like empress, where you should stay few yards away from other players HR is totaly useless. Not to forget about 2p bonus (10% less mana for useless spell).
