I know it's an old thread but...
No, not really. I'm a pretty casual player and there's a ton of stuff in this game I still haven't done and may never do. For example, I did my first ever gauntlet run yesterday and I've been playing for years. So, the idea of an entire new skill just doesn't appeal to me; it's more incoming work that I'll need to focus on at some point.
I also don't love the idea of adding a new skill in general. There are a half dozen of skills that I would much prefer be overhauled instead, like Firemaking and Smithing, without messing up the iconic skill screen.
