Worst offender I've seen is probably Dusk Vigil. The tank had a really bad weapon. Run was awful. It should really be a main stat requirement ignoring stat pots/party buff/racial difference since Ilvl assumes each slot is worth the same amount of power/stats, but they aren't. Main stat requirement would also cover instances where people are trying to cheese the ilvl with wrong stat accessories (seen a tank in neverreap wearing casting accessories) and partially mitigate going in with a junk weapon missing massive amounts of weapon damage. The accessories were changed in SB to be job specific, but the older HW and ARR ones you can still do it with.
