So lets see if this is balanced, or helps make the two mage classes more distinctive.

Conjurer (as of 1.18): 67 Abilities/Spells Total
  • 11 Curing/Raising Spells
  • 8 Buffing Spells
  • 2 Debuffing Abilities
  • 12 Damage-Over-Time Spells
  • 24 Direct Damage Abilities/Spells
  • 2 Crowd Control Spells

Thaumaturge: 50 Abilities/Spells Total
  • 4 Curing/Raising Spells
  • 2 Buffing Spells
  • 17 Debuffing Abilities/Spells
  • 6 Damage-Over-Time Spells
  • 11 Direct Damage Abilities/Spells
  • 1 Crowd Control Spell

So if your keeping score, the better class to invite to your party for Curing, Buffing, Damage Over Time, Direct Damage, and Crowd Control is Conjurer. Thaumaturge only beats out Conjurer for debuffing.

Again, I picked Thaumaturge for debuffing, so I'm fine with this arrangement. But to say that this is balanced, or that this makes Conjurer a more distinctive class is not supported by the existing evidence.

The Development Team will definitely need to make MANY more adjustments in the future.
