Hi there Xerok,
Not sure what times on Fri/Sat you are looking for. We are a Horde guild on Thrall hat raids 11pm-130am server Fri/Sat.
We do much more than just raid though. Feel free to check out our guild spam: [H]Revered with Death - What's your End Game?
Would love to have a chat. Get in touch with Tillae if our guild sounds like a fit!
