Everyone goes in with the "Greed everything i150 and i180", right? Having this would allow people a much easier time with looting. With every single item appearing the same (pink icon, no actual gear shown) it's very easy for people to say "Sorry, didn't notice it was i210" or something. Hell, I've "stolen" an item from my friend recently without wanting to (got a healer item... I'm never going to level healer... urgh).

If all i150 and i180 were just random drops that went straight into people's inventory then this would make a lot more sense.

The obvious downside to this that I can think of is if/when people go gathering. But that should be split out from Diadem as it is.

The second potential downside is "but we were just wanting to farm for our friend so they could get Pegasus, we jut wanted i210" - c'mon, it only takes about 6-7 normal mode runs to get 99. It won't kill them to not get a free ride. And you'll still get i210 options.
