Good job!
Couple suggestions...
Both Tiefling and Dragonborn are now F2P.
(@ new(er) Players: Currently, the only "Premium" races are Aasimar, Shifter and Tabaxi. Warforged is the new Drow, and can be earned with 400
Total Favor.)
"Players new to sorcerer class" may not have Tomes, spec. a Strength Tome, and/or may only have a +2 at best. Recommending a starting Strength of 8 is asking for Encumbrance. It can be hard to notice Medium Encumbrance (-5% run speed), and that could spell disaster for a Sorcie who relies on kiting speed. (Heavy Enc. is -12%, and is pretty noticeable and far worse for both longevity and general questing speed.)
I'd
strongly suggest a comment re new players (without Str tomes) to drop the 18 Con to 17 or 16 (still ample!) and put 3-6 pts into Str. (Imo, when you're paying 3 build points for +1 Con it becomes diminishing returns; there are better places to spend those last 3 or 6 points.)
Similarly, you list 5 skills (+1 option) - but 8 Int with a non-human race (which you indirectly recommend) only gets 1 skill point/level. Some comments in the direction of priority and "Why?" those skills are key might be helpful to new(er) players who could be confused on that point (and or taking a 17 Con and starting non-human w/ +2 pts into Int (and, in this case, at least 1 point into Str).
