I feel like indestructible chaos would be OP since all claws would be eth and sins would deal even more dmg than the ridiculous amount they already have.

The other points are valid but as always not all builds are viable end game it was the same in vanilla d2 as well
maybe barbs can get something similar to assassins with claw block when they dual wield weapons, just throwing an idea out there

For @Game, can you please increase the duration of hurricane to something like 200s instead of 50s, feels really bad to have to cast it so often - I think 200s is really fair and not OP - just less annoying overall
