Uber Lilith spikes unavoidable?

I agree, the entire fight is essentially a flawless run where the player must not make any mistakes while navigating through a maze of ridiculous attack patterns. Why do you think you see a lot of crazy damage builds that push past her first form so easily such as bone spear? Even worse this encounter is impossible to run a team with, so ya the one team member who somehow evaded the spikes managed to live in the tiny circle of death. It feels as though you have to run one of these cookie cutter builds in order to get the job done and skip the mechanics but by then does it feel like you actually completed the encounter or simply chessed it? Why should cheesy builds overshadow and make other builds that are unique to players feel pointless during this fight? How obtainable is capstone to the casual player that may or may not have the best gear as compared to some of the other capstone bosses?
