Hagara you simply sit there and wait until her bubble is up for the lightning one. 5 minutes isn't so bad. If you get the frost one then just run around and kill them and then kill her.
Conclave I just went Anshal, Rohash, Nezir, Anshal. You need a bit of gear but you just kill them in that order. The hardest part is doing Nezir+Anshal before Rohash is back up.
Also I'm curious if anyone has look at CM solo's. I just saw Mione doing brewery and was curious if any bears had thought about solo'ing a CM.
Also fuck Spine. It just requires you to be so careful so you don't get stunned and don't accidentally roll.
Edit: to clarify you DPS Hagara until she casts her lightning shield thing and then you sit there until her cast ends (which is 5 minutes)
