The three suggestions are interesting but I would prefer that Blizzard reorganize the character creation (suggestion 3) because the high elves will be added officially but also the Wildhammers, Sand Trolls, Dark Trolls, Man’ari, Darkfallen… 
Suggestion 3 would allow the addition of new races more easily such as dragonmaws, frostborn, taunka, forest trolls, san’layn…
