I don't have a problem with the old 50 alliance raids. If anything they are quick and can be done under 25-30 mins plus you get a lot of bonus EXP.

I never had a group wipe at Behemoth if anything we kill him before the 2nd meteor and if we have good DPS, we can kill him while he's casting the first meteor. I'd rather have Labyrinth than Dun Caith because of how many times people wipe to the first both because of its death mechanic.
