Why is the healer class basically a one spell dps class?

Part of what allows BLU to be fun is that it is 10 levels behind and can not be used for progression and party finder content. Make it level 80 and allow it to participate in Savage and players will start optimizing the fun out of it.

Blue mage is absurdly broken. If it was 80, it would annihilate savages, trivializing them. Imagine being able to diamondback any failed mechanic.
