So if you've run this since U11, you know it's gotten a bit tougher. Raids are still running it the same as they used to though, which is kinda silly and ends in more deaths and a longer raid. The major changes are that the Reaver tosses more disintigrates etc., and he has a lot more hp.
Given that, it seems like the old "tank until we pull the lever" method is a bad idea. Right now, I'm watching people die while taking forever trying to kill the Reaver after everything is lit. It seems to me that, with it taking so much longer to kill him, it makes much more sense to have more people prepping him during the initial stage, and then after the lever is pulled we can just take him down. Less time for him to toss out nasty spells and take down the party.
Thoughts? I'd like to toss around ideas on making this more efficient with the changes and then maybe we can try it out as a group.
