What would the perk tree look like and would you use it?

All I know is that I have scaled enough of them. I should be able to jump off one and live.

A Climbing skill like Daggerfall's would be nice.

Yeah it's called a horse.

Confused ... The collision detection is so bugged, you can already walk up on pretty much any mountain you want to.

An actual climbing skill would've been great, and would've added a lot of diversity in the way different characters approach the gameworld.

In fact, I think it's silly not having such a skill in a game set in such a mountainous location. This isn't an action-adventure game. Every character I make should be uniquely defined in as many ways as possible. That should include things such as running, jumping and climbing - not just combat.

As a certified climbing guide I disapprove this idea.

Seriously though AC series fills my urge to climb in a video game.

However, I did just realize if you become Ethereal (shout or otherwise), before you jump you can take some wicked falls unhurt!
