How good is Repentance to have as a templar healer?
I'm finding that it feels like a waste of a slot on my 37 Khajiit Templar. I barely noticed the 10% magicka then passive attached to the ability because it isn't on my main healing bar. It's only real use is on bosses with adds whose bodies don't disappear immediately after dying. Since most boss adds do seem to immediately disappear, I rarely use it. Trash pulls are do quick there really isn't a need for it. And it has no direct use in boss fights with no adds.
Does anyone else feel this way? Am I just not using it correctly? Or am I underestimating the use of the skill in end game content?
