I just learned that you won't get the draconic resistance without being a lvl 6 Sorcerer. No exceptions.

Edit: Also Elemental Affinity: Resistance only kicks in if you cast a damaging spell. So.. There are 2 ways to go about this. Either respec later and build towards Charisma, sacrifice Dexterity, then make up for it with Gloves of Dexterity, miss out on getting evasion and an extra feat (bad choice imo) or forget about the resistance and be happy with the AC base that Draconic Resilience gives and only go up to lvl 4 Sorcerer.

This could still be a good combo just for the tools in making your character near impossible to hit.
