Just give it more elemental abilities as your leveling conjurer thats all they talk about is how u feed off of nature. They can put this into whm alot more than it is now, def do something with the mp , yes you can manage it but just in parties where you see other healers healing and they have way more mp than whm makes me sad.

Stone skin two in combat I dont really no why it isnt now shorten the cool down of it. Like someone else said an aoe esuna type ability would be nice. And just shortening some of the cool downs of some of their ablities could go a long way. And just give them something thats kinda always going during battle prob didnt word that right but scholar has the faire, and astro has their cards, give the whm something in between to always be doing while also healing.
