Sorry, I put words in your mouth. That's how I read it. But for how long (hours) were you actually stuck on Horridon?
Also if I can give you a tip, 2-3 hours is not a good amount of time to be raiding. Chose either one and make sure the whole group agrees with it. Ought to be raiding for 3 hours, but generally raiding for 2, is just annoying for everyone involved. Make people show the hell up at time and make sure they don't go on a lot of random afk breaks. Being a casual guild shouldn't change any of the things I named.
