The tooltips would become more annoying for me, but its a good idea for beginners. Most people know what it takes, and how many people would utilize the things in each city? Though, the cities are fine for me, I dont think much needs to change. Flaming Aura is fine how it is, if you say it is "cheap" you obviously suck, becuase its a VERY weak spell, and you can use it at level 1.
For the Priest Idea, thats perfect. Good thinking
