Honestly I don't think scholar needs to he dumbed down. It's toolkit is very synergistic and it plays really well as a shielding pet healer.

They should strive to bring the other two healers up to scholars level, fix whm's petals and 70 skill, give them utility. Give astro it's own identity (as in lose sects) so white mage can shine.

And if they do change anything about scholar it has to be their fairy that heals on no mp and affords them all the gcds to dps.
