Spells.... they take too frikkin long to cook up.
There needs to be something to store spells in when they are done. A spell factory/spell storage can work in the same manner as barracks/camps do.
Or cut the time back for spells. Seriously... 2-3+ hours to cook up spells is entirely too long. It really shouldn't take longer than the time it takes to cook up a hi lvl set of troops.
