The fight overall isn't that hard, all you need is a group that will listen and pay attention. It took me a few different groups to win but the group I did win didn't wipe once. The biggest problems I saw were tanks not keeping adds together, ideally you want to hit them all with one cannon shot, dps attacking adds not the boss (I had one group that told me to do that, and we could never get the boss below 15%, the excuse was "cannons will damage the boss) and people not understanding tethers and the cannons on the towers. Get all of these down and you will win. The fight not hard, as long as people listen.
