Right, because having the least amount of spells known, a rather weak method of recharging their spell slots, and having the weakest spell list out there, makes the Sorcerer entirety balanced, doesn't it?
Tell me about it... The WotC Wizard Boner is so strong and obvious it's ridiculous. Admittedly, the combo would still only come online at level 12 even if it was a Sorcerer spell, but the same could be said for Spirit Guardians.
