Every class race combo can get a 17 in main stat now. Meaning 1 asi increass and half feat/story asi and you hit 20.

Human wizards are finally as mechanically valid as gnomes. About time as lore wise gnomes arnt even close to humans in wizardry might

A dragonborn sorcerer can take a 17 in cha so you can finally play the dragon² ideal and not feel worse than a half elf.

We dont know how strong all of these are, but some weapons and equipment have bonuses if a specific race uses them.

I believe at uncommon it was a 1d4 dice but the higher you go the better these bonuses will probably get. Even if its just 3 d 4 on a a mid to late game weapon that's going to be atleast 12 d 4 total one round with a fighter using action surge.
