Hey, so I was asked to post this. There is a gear requirement for this fight, you can queue without but two things will happen: you won't finish the fight and people will rage at you.
You will need a full set of darklight gear and/or Ampador Keep gear. Not one single piece of the armor you get during your job quest works well here. Also you'll need at least Ifirit weapon or better. You need gear to survive the massive unavoidable aoes that deals more damage then you have hp (but it comes in 4-5 waves hitting every 0,5; so with gear you will survive, if a healer manages to cast at least one aoe heal). Weapons you will need for part of the fight since some of it is a dps race, and even with everyone having Ifirit weapons it will be a very close call, literally one or two seconds can decide whether it's a wipe or not.
Another important aspect is your knowledge, it only takes one person to not know the fight to make the entire group fail. You must know when to dodge plumes (weight of the land) and bombs in all 5 phases of the fight.
This fight is very, very hard right now. Don't expect to do it anytime soon after reaching level 50. Yes I know it sucks, this is the last thing you need to do to get your relic weapon, but rushing will only get you flamed by people you'll end up possibly FCing or partying with
