WHMs in FF (FFXIV) are considered very offensive healer, due to their connection to white magic. Which is actually very destructive, holy is a spell that can potentially destroy a planet.. So I'm sure they get cool damaging spell and some direct heal. AST will definitely get new buffing abilitites. Maybe double draw? combine bole + balance for new buff etc. Or new cosmo buff. SCH is all about the nature balance, coming from their history, I can see them getting new AoE DoT.. but honestly. SE likes to find a connection between skills and make a new one that is easily accessible. So we just need to bring all the Sch, whm, ast spells on the table and think.. what new spells would be that don't let other skills down.
