My points are that, for example, a Warlock has d8. Why? Did his patron give him/her more fortitude? Then why can't a Sorcerer's innate inner magic increase his fortitude.
I agree with a post that the Wizard is the "poster child" of D&D. But if they need to make the Sorcerer stand out more than Sorcery Points. I do like the suggestion of giving more skills, thereby making the Wizard a great spell utility character and the Sorcerer a jack of all trades.
Above all else, I would have preferred if they would have increased their spells known to 20 to 25. It's a slap in the face to have Arcane Tricksters and Eldritch Knights know the same number of spells.
