Shadow does have a good suggestion about limiting spell stacking. But it would/must be dealt with on the "honor system". I won't inspect any ones build. You usually do come up with helpful ideas!
And Hugh, as always your suggestions are thoughtful, mostly concise and peppered with humor! Not to mention good!! Dark Bead is definitely on the "Hit List" as are Fire Surge, and Tempest.
Being on the "Hit List" doesn't mean they are gone yet...but their demise is seriously being considered.
