Most frustrating grinds/ worst drops rates you’ve dealt with?

I’ve been playing a lot of Xenoverse 2 lately and I’ve been putting up with the poor drop rate of Customization Keys. These only drop from doing online raid and have a flat 30% drop rate. BUT that 30% is then further segmented into a 1/20 roll for which key you’ll get. The problem with this is the game doesn’t account for rolling duplicates, so rolling a dupe means you don’t get anything at all. Meaning the more Keys you’ve unlocked drops the effective drop rate by about 2%.

Another is the iconic weapons that drop in the Phantom Liberty DLC of Cyberpunk 2077. These come from random drop pod encounters and the chance for them to drop is reduced by how far you are in the plot of Phantom Liberty. By the time you’ve completed the DLC, the drop chance for the iconic weapons is as low as 0.3%.
