I'm a Corruption Sorcerer, 333ilevel with some augments. I usually have a Juggernaut tank, Assassin, and another melee. All around the same ilevel and augments. We have tried several times to complete this flashpoint on Mastermode and we always get stuck on Master Oric Traless. We kill the datacron before his cast ends, no one stands in purple circles, but there's just so much AoE. He constantly casts debris and sometimes it hits for over 100k. Before I thought he only did that when someone got low, but this has been constant, even after they've been topped up to full. I understand it's a heavy AoE fight, but this is unhealable. I've watched videos to try and see what I've been doing wrong, and I notice that in the videos, the random purple circles of falling debris (not the phase where it follows you) falls a lot slower than the attempts I have done. I just came back from a hiatus, so I know I'm a bit rusty, but I don't remember it being this difficult. Any suggestions to what I'm doing wrong, or what I could do, would be greatly appreciated.
