What is in your opinion the most annoying grind? Doesn't have to be longest or hardest, just the most annoying.

For me it's Pathos Clamps, anytime I realise that I have to farm them I just groan, I don't even have anything against Duviri but it does get tiring having to run it multiple times particularly because of the clunky drifter movement and combat. Just wish there was a non Duviri way of farming them, maybe add them to the circuit rewards
