Rogue thread has an awesome rundown on all the fights (tips and tricks).
It would be so great to have a shadow/disc/holy version of these too. (when to pop PI, when to blanket raid, use party heals, etc etc).
I have a good understanding of some of this, but I'm sure there are way better suggestions than mine out there. But maybe we can work as a community to come up with this list? What do you think?
