That’s the thing ilvl is functionally not the same in UCOB because of the changes to the way gear works since SB. It’s hard to compare with pre ShB content because of the changes to ability to meld mainstat, food and potions, accuracy, agro control and 10,000 other things

For post ShB it’s primarily ilvl bloat because the game doesn’t sync properly

There are outliers where potency is the problem (PCT in dungeons between 50 and 70 is hilariously overpowered on potency alone) but OP’s given examples of EW alliance raids is ilvl bloat, not potency creep
