Is there a point of doing something harder than turn 5?

So turn 6 doesn't have to be harder then turn 5 to fit into the flow of boss fights that most raiders are use to dealing with. The main issue I think you are referring to is that people in all 90 gear will most likely destroy CT, and some feel no need to even do it. I like to raid to fight different bosses, so even if it is easy, I might have fun doing it, but not everyone feels this way.

Yes, I have raided in other games before. However, FF14 follows the 'attunement' pattern that dictates that the next boss tier will be harder (You have to kill HM before extreme, Ifirit before garuda or titan. SE will require people to finish T1-5 before they can tackle T6-10. The only way to challenge people who has finished T5 is to make T6 and above as unforgiving as T5.

This is what people have stated what they want - harder challenges, better loot.
