This post pretty much shows exactly how each of the champions act and why they attack who they attack, if you take this stuff into account you can possibly get a greater degree of control over the fight and save some lives. It's really only useful for PuGs and Heroic mode since they aren't that hard otherwise. The info about how the champion healers work is pretty useful for everyone though I think, all the time.
Some pretty cool info in that post nonetheless. Not sure if it's gotten around a lot or if many of you have seen/know all of this, but for those that haven't read any of this info it's a pretty cool read.
As I read through it, I found myself remembering certain things happening often throughout all of my FC attempts and going, "OHH that's why that happens!", like Warlocks dying first ALL the time, lol (explained in the post).
Anyway, most of it looks legit, give it a read and pass it on to your guildies! Also, let me know if you've seen/heard about this info before, I haven't but I could be living under a rock
