correct me if im wrong, though im about 99% sure im not...
but im do recall several months ago a mention of a troll raid being added in this expansion, a ZA type of raid.
It would have been nice to been givin another timed event type of raid, with rewards givin to you for your efforts. hard modes are nice, but its not the same.
(before ppl troll me saying you just want a free warbear-piss off i have one)
