To those mentioning the Lieutenant Weapons, it's true that you need AK to hit that rank if you didn't obtain it in 1.0. However, what people miss is that Wanderer's Palace drops ilvl 55 stuff, including weapons. Lt Weapons are also ilvl 55.

If i'm in AK, I usually only balk at people who come in with something under 45 or a white weapon without any materia at all. I don't tell them to leave, but I do tell them we may not be able to finish, depending on how bad the gear is.
