Totally agree with the OP.

I was in a LS on XI that had done everything outside of AV back when it was unkillable, none of it took any skill, it was just a roll of a dice on drop rates or claiming the mobs. There was hardly ever any thinking into any of the encounters that ranged from Vrtra, Tiamat, Jorm, Khim, Cerb, Fafnir, Nidhogg, KB, all sky gods, sea NM(outside of AV).

XI's endgame is and always was a joke, there was nothing challenging besides getting claim on the mobs and hoping the dice rolled in your LS's favor with drop rates. The only challenging fight was pre-tp zerging Bahamut V2 because things could go very wrong but everyone and their grandma started melee burning him.
