This 'zone out for 30min' or 'soft instance reset' thing is annoying where they give it as a needed fix.

Ever do the rend even and while fighting Gyth more Chromatic dragonkin and orcs show up? And when Gyth dies Rend doesn't dismount from Gyth? and then more waves of Chromatic dragons and orcs and then another Gyth, eventually resulting in OOM and multiple Gyth and no rend and the gates never opening for you?

Yeah, 'zone out for 30min' ...
