And let's not forget the random BoP's, Vortexes and patterns you will get clearing to both Lurker and VR. There's some pretty good BoE and BoP craftables to be found and made, your crafters and weaponsmiths will love the Vortexes (should get 1-2 at least clearing to either boss) as well.
By all means, every guild should give it a go if they can field the 25 man. The change of pace, new environment, heck even the the overwhelming truth of getting your arses kicked should be a good boost to any guild interested to get a taste of endgame raiding
