recently i was prepareing for raid on wizard, took me a while to set up spells, and then again took a while to go back to usual non raid spell setup. i got idea then
why not have a spell book sets similar to weapons, complete spell book saved as set with description in tooltip what its set for, if turbine would like to make money on it, base number of sets could be limited to 2-3 with others above that unlockable in ddo shop.
