I was going to suggest that defensive spells that can only target you should have concentration removed. This would bring blur, blink and stoneskin more in line with spells like mage armor, mirror image and flame shield. But then I realized that if concentration were dropped from each of these then they could all be stacked at the same time to turn the wizard into some sort of super survivor. I personally don't like spending concentration on self defensive buffs as they feel like they don't affect the combat as much as other spells but without hacking together some alternative to the concentration mechanic to deal with them it seems like it might be necessary. Unless someone can think of an elegant solution.
