Legerdemain: Improved Hiding needs to be replaced with Medium Armor: Improved Sneak. Medium armor should not be a requirement for improving stealth skill. A light armor spell caster should be able to sneak just as good if not better than someone in medium armor. Of course Heavy armor wearers should still be allowed to improve stealth but penalties should be added for trying to sneak around in heavy armor. Training in Stealth should not be placed in a single armor weight it should be on its own, placed in one of the night blade passives, or taken out completely.
