This fight is really complicated and there are a lot of moving parts. I have created a thread to get input on how we should tackle this fight.
I am going to list some guides and videos I have found on the web to help consolidate our information.
http://www.wowhead.com/guides/xavius-strategy This is the wowhead strategy guide for Xavius. This wowhead guide has some really good diagrams that show how we should position the raid in the different phases.
This guide also gives detailed explanations on what each raid role needs to do in the different phases. Please read thru the guide.
This next link is the Fatboss Video from beta testing.
Heres another video from patch day from a hunter perspective.
This is the newest Fatboss TV video for Xavius. This is pretty much how we are going to do this. Please watch this video before the raids. This is very important. We will be referencing this video when we do Xavius.
Please join in the discussion so that we can take down Xavius in the coming weeks. All input is valuable. I will update this main post to show our strategy.
