It enraged, so did I, and so probably will half of the people who are arguing in this post...
Unlock Blue Mage, fight Bombs in Thalanan and learn the spell Self-destruct.
Use Self-destruct near the sightseeing log you want to get, and have a friend raise you up on the spot.
The bad part is, it has a 10 minute cooldown, but it should be OK.
I don't think the jumping puzzles should be changed at all. There are ways around it if you can't complete them for whatever reason.
First off: I support any accessibility that is possible and will help ANYONE. But here comes the twist for any dev:
How deep are you going to apply it?
Blind people?
Nearly blind people (dozens of illnesses are out there).
And by any means the content must of course also be usable and enjoyable by healthy people.
This post is not to make you feel worse or less supported. Just trying to add a difficulty level which is fully on devs and maybe - just maybe - it makes you less left out knowing that even devs are struggeling with that question on a daily basis. In any game and provided service btw :)
The sightseeing log as a whole could easily be called "an optional fun bit", since it doesn't really have a functional purpose, but you make a good case for making jumping puzzles separate from the sightseeing log.
The sightseeing log is typically just about exploration, so these unusually difficult platforming bits are probably unpleasant or out of reach for many players who like the rest of the sightseeing log, while the rest of the sightseeing log would be of little interest to players who like the jumping puzzles specifically. Though, I don't think the jumping puzzles themselves should be removed/made as easy as Leap of Faith/omitted from all future zones, nor do I think there should be no reward for completing them. The sightseeing log entry associated with each jumping puzzle could easily be replaced with an achievement specific to that puzzle, maybe with a small reward like a minion or a title if you complete all of the jumping puzzles.
There's a balance to these things. An MMO can't be designed for only one type of player, because games like this try to appeal to a wide audience. Pick any random player, and you'll almost certainly be able to find something in the game that they find too unpleasant, too difficult, or too time-consuming to complete...and yet, that player's favorite activity is probably someone else's impossible task. Considering that, if these jumping puzzles really are one of the only things you're unable to complete, you're not "less than other players in the eyes of the game". Rather, the jumping puzzles might be one of the few things bringing you down to everyone else's level...
Then you'll have OP crying about how they can't get that title.
Some things aren't made for everyone. I wish I had Ultimate weapons, for instance, but I'm not making posts about them dumbing down Ultimates
Some things will remain out of your reach and that's ok. Focus on what you can do.
And as I said before, the Kugane tower can be circumvented with Self-Destruct, or an EB ring, without having to water down the experience for the rest of the playerbase.
