Farming hundreds of hours to improve your damage and defenses becomes useless if a Boss bugs, glitches, overlaps phases or becomes suddenly immune.
This problem has been around for years, especially with Andariel, Duriel, and Beast in the Ice.
This Season is worse.
They need to balance the damage or at least add visual effects (like shield in Last Epoch) so can we understand that “we have to stop playing”.
Seems that Blizzard only cares about players who barely get to Torment 1 and do zero Burst damage.
