So ISYF as a raiding guild started nearly 4 years ago now, and we've had a lot of success with the format really. Expanding to 20 man has worked reasonably well in some respects- we got raids together, cleared up the heroics and down some mythic ones- but overall the feel of the raids just hasn't been where we want it. Honestly, I think this is largely down 20 people just being too many people. The format of we wanted for the guild was a struggle with 10 people. With 20 it's significantly harder, and we've decided to give up. As a result, we've decided to stop raiding as a mythic guild. It's been a blast raiding with you all, but I think we've come as far as we're going to go.
ISYF will continue to exist as a guild, so people are welcome to stick around if they want to. However I suspect most of you will want to find mythic raiding guilds, and I wish you all the best in doing so. Feel free to poach other ex-raiders for your new guilds :)
PS: We killed Blackhand heroic last night, which was a good way to end it really.
