I am a tiny bit conflicted about the EK changes now because
Tried to build a pure caster Sorc15/EK16/Barb2/AS7
people are going to abuse EK for their AQ casters, just as above.
As said, the biggest issue EK's face because they are a MAD class, is that they have to be built in easymode or built with specific class combos that wreck their CL otherwise (12ftr). Imho EKs need something that will allow them to max int, and still hit ~80+ AB that you basically need for endgame.
If you aleviate the power that EKs need with a bunch of bonus feats, they are just going to be abused as a feat mule aka. hospitaler with full casting progression. (-1)
