Yoshi-p and dev team hate classes they want to remove it complete. But can't do during how it tie up with 1.0 bad decision with classes. They try it with smn and sch with acn but it went backfire to them with balance and animation issue. Each expansion you can see how they try remove smn and sch connection bit by bit.

It just like how much they hate to create playable new race/face for us cause it tie with core system 1.0.
