So after the patch it seems Tytalos has not been changed and is even harder?
The sand move is still a 1 hit kill. I died to it trying to help a friend on a 1000 ilvl berserker and had gunlancer friend with similar ilvl die as well. Both of us had full health each time and once he even had his shield up.
The bigger issue is that the sandstorms no longer spawn after the first round. This makes the fight really difficult as the only method seems to be to try and cheese a ladder or just run away.
