Absolutely no fun on Sirus last phase!!!

100% Agreed. This boss is a joke and they know it.

This league is the first league for my that I made to the endgame. I never killed Sirus before but this league I managed to kill him on A8 as well as all other end bosses.

I played redemption spectres and because of harvest, I managed to score some really good gear.

But the Sirus fight... I had I think a total of 8-10 failed attempts (no portals left) before I killed him.

I would make it to last phase with all my portals still up to lose them all in the last phase, happened multiple times. The time I killed him was just because my spectres had so much damage I could zerg him down.

I know there are sound queues, chat queues and whatever but I had two pairs of rotation beams a few times, death beamed while entering, even after fully learning the fight it's just one big mess.
