Why would it be too late 
Just need to play the game a bit i have alts so essences not an issue and I got him to 450 almost in a day from 380…
Might take a bit to get em up but it’s kind of fun to learn something you never really did. (Used to only dps)
Edit - I dunno something kinda fun about the disc playstyle…its kinda clunky but addictive in terms of trying to decide when to panic heal vs atone heal lol…
2edit - Thanks Alphion, got him to 450 and it’s so much fun to be able to do decent damage and in my case avoid and “counter gank” a lot of fellers that figure I am going to be easy to kill
I did take a few different talents though, how come moment of repose instead of more damage ?
