I've only done the Discovery Tours in Origins, Odyssey and Valhalla so far, but one thing has annoyed me in all three: the fact that switching to walking instead of running won't stay toggled. I prefer to walk rather than run (for one, it's easier to control. For another, I can take time to look around when I'm walking). So I press the appropriate key to walk, and everything's fine.
Until I talk to someone. Or otherwise interact. After that, it's back to running again, and I have to toggle back to walk *again*.
This gets annoying pretty quickly. Is there any way of keeping movement speed at walk, while still being able to run if I want to?
