Honestly OP, I saw your breakdown and I think you just interjected your bias on the classifications of fights. All of the fights you listed have ramping difficulty throughout them. And the ones you call horrible, are just long epic fights. Phase 5 in turn 5 is one of the easiest phases of that fight and I had less wipes in phase 4 than phases 2 and 3.

I feel like your opinion is that longer fights with multiple phases are things that you don't like, rather than ramping difficulty. Since T1,T4, T7, T8, shiva ex, Levi ex, garuda ex, Mog ex all end with more difficult phases or abilities than they started the encounter with. First coil is hard to judge now due to gear inflation but those fights had ramping difficulty throughout the encounter.

T2 is hard to judge now because most have never experienced the non enrage mode, which is a significantly better encounter design than it is now. Though still not one of my favorites but it had nothing to do with ramping difficulty of the fight. (It is more that you had to clear trash again after every wipe...)
