Now I don't know if they ever changed anything since launch. But if you judged the max speed by the first flying saddle you got you didn't actually experience anything close to max speed. Pals that have their saddles unlocked at a higher level (usually) have a much higher speed when mounted.

Dunno if you were aware, but there's an easy tech you're able to use to get actually good travel speed. Slide down a hill, any slight decline really, and jump into a glide. Slide momentum is maintained into the glide, and any glider will give high speeds. It's the best way to explore by far.

I'm not entertaining the idea that shifting to a critique of a specific aspect of the game is the same as claiming it's "boring".

Also, I think the way they paced out the increases in mobility is one of the game's stronger aspects. In the context of a large explorable world, making walking speed too high will destroy the challenge and pacing of the game like nothing else. The overworld is enormous with appropriately scaled terrain that's magnificent and glorious to behold. If you're not taking the time to look around and appreciate the scenery, I can understand why you'd say it's "boring", but maybe consider that it's not for you and move on instead of pretending your opinions are able to predict how appealing people find it.
