well, we can TELEPORT around... no need of traveling. Imagine if the Fellowship of the Ring had access to special rune spread across the land so they can teleport around in a instant from rune to rune
Imagine if the Fellowship of the Ring had access to revive scroll, Boromir would still be alive

I always assumed that fast travelling is travelling that does happen, but you don't see it. A good example of fast travel is Red Dead Redemption 2 where Arthur's beard grows during fast travel. That is why I don't agree with teleportation runes either but that is just being too picky, leave the runes if you want
Gale's introduction says hi, along with his explanation of how it worked.
Imagine all the time required to make a different camp for every possible area a player could choose to rest in. There is also this glaring problem that I see, right off the bat, we're on one map, with an excursion into the Underdark. Is Act II using the same camp? What about Act III? What is it that you've seen that the rest of us hasn't?
