Trains are not what I'd consider fast travel and I've had the camp option since the opening of act 2, but it's one way. I want fast travel from wherever. Makes me not want to go far from camp because ugh that ride back.
I understand wanting players to experience the world, but later on I just want to get things done
You can fast travel via stage coach or train (for a fee) or one-way out of camp with the fast travel map (if you've purchased it).
