Relaxed Intensity
You will have to exemplify that claim.
(Please don't suggest I am basing my criticism on ignoring core rules, it is unbecoming)
There are rules for how climbing works. They are short, simple to comprehend, and let you know exactly the latitude they provide the GM. If you follow those rules no feat will cause you any issues.
I get you do not like the game rules actually having an impact on basically anything except combat, but it's obvious PF2 is not trying to be that type of game. It's been obvious since Day 1. It's not some breaking flaw. It's just not the design decision you would have made.
