Simple Solution to BLU

[Fornix]

Then everyone would want Tank Paladin, Healer Paladin, DD Paladin. And the list goes on, way too many soul crystals.

Would it really matter?

All 3 roles within a single class after all HAS been done before. It has been a long time since I played world of warcraft, so I'm completely unsure whether it currently still applies. However, Paladins there could be Protection (Tank), Holy (Heal) or Retribution (DPS). They have the trinity within the single class. Was Paladin the only class played due to it? Not quite.

Plus really by the time that a blue mage would be introduced, does it still matter for a person to have a tank, heal and dps within a single class? Is it not like we already have all those roles on a single character anyway?
