Well, I'm just so glad that Blizzard's CM is maintaining its high standards. It reminds me of the halcyon days when Fear would break in a new way every patch.
(And I'm not taking the summoning issue into account here, if that's a legitimate exploit issue. This was just egregious, and a perfect example of why you never ever EVER EEEEEEEVER push something live that is only on your internal server when you have a perfectly good PUBLIC server where people are telling you things are not working properly.)
Heeno: Sundial only procs from harmful spells; it never procced from Fel Armor (to my knowledge).
