There's genuinely nothing "tactical" or "more challenging" about watching your party walk across an empty map that you already cleared 6 hours ago because you forgot to grab something. This is a terrible suggestion. Maybe this is to prevent vendor cheese or something, but I think one of the most boring aspects is forcing somebody to pointlessly walk from point A to B on an empty map they have already cleared dozens of times over for no reason. Its not like there is an exhaustion or attrition mechanic for walking, this just saves time and sanity.
I absolutely agree. However, right now, the game lets you teleport when areas are definitely NOT cleared.
How about something like: when you enter certain areas, until that area is secured, you can teleport, but can't long rest or change your party?
