For this, you cannot cast healing spheres anymore when youre silenced, they fixed it..you can check if you want the problem is they can still cast enveloping while being silenced and healing spheres are bugged here but its a bad bug, youre not suppose to consume any spheres while in full HP and its suppose to be shown red on the other side fighting you, its suppose to stay in 1 place if theres no one hurt, if they're going to fix that it would be easier to heal someone in 3s instead of spamming surging and losing alot of mana
example ret/frostDK/rshaman, ret/survivalhunter/any healer they can just burst your mate and lose alot of mana because Ret pallies mastery is bugged, Survival hunter doing 100ks serpent stings o.o they need to fix that.
