How are you enjoying whm? And what do you like about the game?
If you’re impatient to get a healer to end content I would continue with whm. Why set yourself back 30 levels on account of what people say about whm. It’s still a viable healer.

Leveling another healer via daily roulettes and some deep dungeons isn’t hard but it’s nicer if you already have a capped class tbh. Doesn’t feel like you’re in an endless leveling phase.

I would also advise you to level it the old school way, nocturnal plays differently and getting cards and skills as you go really helps you learn the class.
