WHM getting progressively more unnecessary in content?

[Yeol]

Except this is exactly what AST is. It can heal as good as a WHM, mitigate better (even in diurnal), can reliably DPS more and offers great utility.
This is everything a healer is capable of. And it can do it all.

Also I know a popular argument is that WHM si a simpler healer, but this is really not true. Just like Monk not doing that much more DPS than a DRG, WHM doesn't heal so well that it achieves something an AST cannot.
If WHM heals were so strong it completely simplified mechanics and raid damage that would be different, but 90% of the time they heal about as much as an AST does, with the difference in healing power only being shown on paper, not in use.

I've already said AST is the WAR of healers now.
WAR can hold aggro, DPs and self heal efficiently (He can do it all).

Doesn't mean WAR and AST should be changed. Not many people play them to their full potentials, but they can make wonders when played well. Nor does it mean other jobs should be brought to their level.

WHM is only missing MP recovery. That is the only thing that will really fix them.
AST and SCH have no MP issue compared to WHM. Give WHM a better way to get MP back and they will be healing+dpsing, then no one would mind having them.
