I'm not a fan of the new cross-blooded evolution for 2 reasons.
The first reason is that takes away a key difference for me for divine and occult casters. Now , I struggle to find a reason to play an occult or divine sorcerer over a bard/cleric/oracle. (This doesn't affect my decision for primal/arcane).
The second is that the blood magic effects are a bit to fiddley for my taste. I have to make notes on all my blood magic spells about the effect as a reminder for 1 round effects. With the new feat, I will need to make additional notes.
