I'm stuck at 70 and will be willing to help get up a bit, I also want to do some Assault missions if anyone is up for that. I have 86NIN and 84BLM which will both be 90 very soon^^, send me a tell in game if you need me :)
people already have done nyx floor 1-40 in 4 40-60 in 5 60-100 in 6(if lucky also on 5 player) at lvl 75 so if you have some experience try it also on lowman is more fun maybe:)
