You define need as ilvl upgrade. That is not the only definition. When labyrinth was 1st released with ilvl below coil gear an interviewer asked why raiders should bother with st. Yoshi ' s response? We hope they will participate to obtain glamour items or gear additional jobs. You define need as ilvl. Devs and many players say that's a bunch a baloney.

Choosing not to need on gear you can and being mad at others who choose to need doesn't make the system unfair. It makes you dumb for giving away your lotting rights on principle then being mad others aren't doing the same. If everyone uses the need function no one gets screwed over. If your mad you can't get specific gear for a different class, then go play that class.

There is no unfairness, and being 'nice' and never using need doesn't make you deserving of others to return the favor.

But the root of it is that you refuse to accept that ilvl is NOT the only legitimate reason to need.
