Fast travel is only fast from the players pov outside the game.
Ingame it takes the same amount of time it would take to manually travel to a destination if the journey was uneventful.
Basically it's not a teleport button... it's a "then after an uneventful journey he arrived at Windhelm several hours later" button.
So imo it's perfectly valid to use in an RP context.
Yep.
It's a regular "scene transition" type thing.
"Later, that night...."
"Several hours later...."
"Uthgerd traveled back to Whiterun. Having helped pacify the bandits and being familiar with the terrain, the journey passed uneventfully."
Not really a big problem to "RP". :shrug:
I enjoy coming up with creative excuses for being lazy
I find the easiest method to be.... don't consider it "lazy". Consider it a valid gameplay option that the devs intended for people to use.
