if it up to me i would add a few more races, or even more something that fits the companions in the game, for example aloth : in lvl 12 can become archmage and bind to himself a robe of the archmage that made from ivory and gold or maybe in level 14 he will have to choice between the path of the dragonborn or the path of the undead (only if he want to) , if he chooses the path of the dragon , out of his shoulders coming out a nice red wings, if he chooses the path of the undead he can do a ceremony that make him a lich wizard ... both i think can add a real flavour to aloth character...
i would add an half-giant race and thri-kreens , half-lizard , for the ranger i would add amazing companions such as : unicorn, hipogrhiff , gryphon...
something amazing like that...
