Worse fight Kateryna or Sirius?

Both of these fights are terrible, but what is worse?

Sirus by a ten fold you can actually brick the fight too on Sirus lol

I hate the mastermind, but only because u get the same loot from a level 60 encounter and a level 83.

Sirus actually is farly easy and won't reward and encourage lowcontent farming like the mastermind used to in betrayal

Sirus is rather tame imo
After the storm phase the only hope of him killing u is if ur dumb enough to take the huge multi lazer or fail the meteor maze.

Catarina is not even comparable, it's a little unintuitive but once you know how her mechanics work it's a walk in the park.

Catarina by like 10x, i dont like her fight because she teleports all over the place and is immune, but with the changes over time that fight got easier. Sirus is alright if they fix the storm spawn on entrance part.

Give me more fights like Aul or Cortex that have a clear pattern and get harder with different modifiers.

Worst mechanic ever.
Makes me want to quit the league or even the game until this gets changed somehow.
I don't mind hard bosses but this fight is simply stupid and not fun at all.
Running away from clouds? How is that enjoyable?

Sirus is one of the worst things to ever happen to poe and solely because of those horrible chaos storms.

Awakener fight is just terrible

Mastermind fight is by far better. At least something happens during her immunity phases and the mechanics are well displayed and makes sense. Sirius fight is just a bug-fest compared.

Why pick one over another if they are both terrible?
