I have added the Heroes of the Elemental Chaos Wizard class, the Sha'ir. This gave me 5 Wizard classes so I went to d6 with 1-2, the Arcanist, the most common option.
I have also made the decision to take the Wilden off of the Rare Races table and replace it with the Shardmind. Shardminds are very, very rare though some still exist.
