Hiya, for starters this is not teach me how to holy heal, more looking for advice on how to improve further.
That being said, lets start off - im raiding in a 10 man raiding guild, where the healing team 99% of the time consists of a holy pally, resto shammy and myself as holy, my experience is 8/14 hc.
I've have recently changed my entire playstyle to renew based with 13k haste breakpoint - used to be more mastery oriented with 1st renew cap on glyphed - and focus more on PoH and chakra stance dancing as far as possible.
I clearly see the diffrence on those 2 playstyles and the renew i find superior on most fights, some exceptions like siegephase on jugger hc, where the bursthealing from FH/GH/HW is better and more required, that said, i do keep renew on ppl with the ticking dot and tanks, keeping renew on everybody durring siegephase, preparing for the shocks and cascade after that.
Other fights like malkorok, i dont use renew at all where i resort to PoH spam, but not sure thats effective enough (never killed him hc)?
Considering, when i get a few more haste pieces to go for the 18k haste cap with glyphed renew for more concentrated healing instead of longer duration.
