Point of the return to NLC scroll?

If you're that close, you can leave through the Bent Tree portal (the middle one) and head back to the House.

And if you're still on the mountain, you can run back down (surely if you've gotten this far, you know how to get back, right?)

But really, return scrolls tend to be what you always have. Just like you don't walk from Zakum to El Nath, you don't go to CWK without any transport back.

im just saying, what if they're lazy or lost...and for the "return scrolls tend to be what you always have", some ppl might not be lazy, and therefore they dont have the return scrolls...and some ppl think that they are a waste of money because they think they could just walk there instead of using those.
