Personally I feel that Raise/Resurrect spells are a tad too high in the leveling spread of Thaumaturges and Conjurers. With the current level cap, we basically play 2/3 of the game having to run back from the aetherite every single time we die. That's a bit too much.

I would lower the level of Raise/Resurrect to somewhere around the mid-twenties, like 24-26. That would be, In my opinion, much better balanced. Seriously, there's already too much running to do in this game
