Our crappy casual guild Zirkel der Heftigen on EU-Alexstrasza downed Void Reaver yesterday.
It was our 3rd ID in TK, we haven't even tried SSC or Magtheridon yet. My guild has been raiding 25 mans only once a week.
Even though we had a lack of dps and healing it was enough. 2nd Try last night, 10 min 1 sec (that's how it felt), and I got myself a tiny little T5 shoulder token which I turned into Def armor as my Arena2 shoulder are good enough - the difference would have been barely noticable.
If I manage to get the image upload function to work, I'll post a killscreeen (I have nothing but trouble when I try to upload images - I get not feedback at all, and it doesn't matter wether I choose IE or Opera....).
