This is primarily regarding PvP.
TLDR: Ancestral Guidance getting removed is okay as long as it is replaced with a useful, non frustrating way of off healing. For example: A pvp talent that makes Chain heal or Healing surge instant for ele (maybe after a certain amt of maelstrom is generated?) + increases their healing by x% would be good as that is an active way to offheal rather than passive via AG, but will reduce the amount of casts ele would have to spend on off healing (a lot) to make up for the loss of AG.
Longer thoughts:
Ancestral Guidance is essentially always combined with Ascendance, so I understand the removal of it. Its entirely passive at that point. However, Healing Stream getting an 80% buff does not make up for losing Ancestral Guidance at all.
Ancestral Guidance is almost always my top healing as Ele, in some arena games it is doing 9-12m+ healing, sometimes more, and those are usually 4-5 minute games with 2 uses. In Rated Blitz/RBGs it does a lot more, usually 17-20m healing in a full game.
If an ability that powerful is being removed, we really need to see more than an 80% healing stream buff. Maybe a way to make healing surge instant for ele+heal for a bit more? or maybe a way to make chain heal instant for ele and heal for a lot more? Something we can spend globals on, ideally without a cast, that will do decent healing.
If ele has to spam healing surge to make up for the loss of AG that is going to feel pretty terrible, and even then it won’t do as much healing as AG. The major benefit of AG with ele is that you had this big healing CD during your own offensive CD, making it a bit harder to stop an ele from doing damage during Ascendance. Having to cast multiple surges during Ascendance and outside of it will be terrible, so please maybe add a way to make surge and/or chain heal instant for ele (maybe pvp talent) so we have a way to actively heal without spam casting.
