I'm trying to basically take where it is in the 3.5 system and shift it into a similar place in Pathfinder (that is, I'd like it to be similarly powerful in comparison to the rest of the classes as it is in normal 3.5), with perhaps a little bit of a relative boost. So, I'm not looking to up-tier the class or put it on a level with wizards and the like.

Also, I didn't see Eldrich Glaive in CM? In fact, I saw 2-3 invocations I'd even think about taking, and those are pretty much overshadowed by other things. Am I crazy?
