Okay so looking at the new write up and spending two hours reading the four hundred-and-something posts, my biggest gripe is I don't feel the Sorcerer anymore. With the Old Arcanist you could spend a power to get bloodline ability and there is no similar mechanic in the new class. The only thing of any Sorcereriness is the spell Casting they get. As for the Exploits, I see evocation, evocation, evocation, Conjuration (teleportation), evocation, evocation, Abjuration, Abjuration, and then some more Evocation.
I don't see any ability to support someone that would want to play an Conjurist, Illusionist, Enchanter, or Transmutist and mix it with a bloodline to get a boost in thier none combat abilities. All of this I felt was accomplished in the original run of the Arcanist. The only disappointment the Player felt was that they couldn't get a familiar due to the Arcane Bloodline only being in effect for a number of rounds per use. but now she doesn't want to play the class since the majority of exploits are combat-oriented and there is nothing for a versatile caster outside of combat.
I feel that this could easily be rectified by having Exploits more aligned to the afore mentioned schools, and for there to be Exploits to take some if not all of a bloodlines abilities for a number of rounds akin to the old Blood Magic ability. This way it moves back to the Hybrid build that I thought Paizo wanted for it and less in the way of being its own thing and a completely new class. I might be wrong in this, and this is only my opinion.
