I have been considering playing a Tiefling much more on the strong than on the agile or magic side of things, though whether he'd use that for a Barbarian, a Ranger (think of a very strong bow or a crossbow) or a Rogue route (you don't need to pick the lock if you can break the door gently without using momentum) is still pretty much in the open. So I'm flexible if there are any concerns. Assuming that any of those routes makes sense of course :)
