To me, Fun can come from different sources, mainly relaxation / entertainement (I call it "the vibe"), and focus / accomplishment (I call it "the flow"). These are two very, very different streams.
High End Raiding isn't supposed to be fun from the "vibe". It's for the "flow" crowd, who are seeking accomplishment, and get off from overcoming limits. Some are seeking the gear, yes, but I can tell you all are mainly seeking the challenge, cause let's face it BiS gear is useless if you don't parse (or go Ultimate, and even there it's later dungeon gear that is BiS, not savage). That's a small flaw of this game but eh.
There is a way to upgrade ilevel with more time, which is the hunting and the 24 raid both coming 5 months later. But indeed it's only for tome gear so not complete BiS. Maybe the system could be improved so that you can buy Savage gear with 2x2 raid 24 pieces for instance, after the limitations are lifted. For people who are really reward oriented.
I wouldn't be opposed to it and even as a raider wouldn't feel my own accomplishments tarnished because people get the same gear 5 months later : it WILL rot anyway in a few months given the vertical game progression design.
I would much rather have that, than difficulty lowered which would ruin the fun of the game for the "flow" people.
So OP, maybe that content isn't for you, OR maybe you just need a bit of patience and improve little by little and you'll get there. Back in the days I started the game my FC brought me in T5. I thought Gemellia was the hardest content I'd ever face (and fail at it). Now I regularly kill Savage 4th floor and parse okayish with my reroll's roster (granted, Savage level has dropped a bit with each extension. Except E8S, shit was as hard as Alexander in min ilvl). And there are even better player who clear ultimates. I progress in it but don't have the level / dedication.
My point is : you can come from "meeeeh, extreme is hard" to 1st, then 2nd then 3rd, then 4th floor level. Just takes time and patience. And practice. A lot of practice.
