So i just started playing the game yesterday and my main aim is to eventually do mythic plus till +10 keys .
So i have seen some debates here on forums about how holy priest is not in such a good place .so my question was is holy priest doable to +10 keys ? As i am not running behind 3k score but rather just the +10 keys maximum .
10s are absolutely doable as holy priest. You will have a harder time than on other healers, but that shouldn’t hold you back if you enjoy the spec.
Thank you for your answer.
Havent played holy myself for a long time, so cant give much valuable feedback. But as of the time of this post, the only healer in the world that has done a 14 key now in s2 is a holy priest, in case you need some inspiration 
ty thats very much encouraging
Holy is a LOT easier to play as compared to Disc.
As Holy you can just focus on your player frames/grid to heal over… as Disc you’ve got to deal with dps’ing too.
