Well in that case the problem still remains. The problem being that in combat you can never close distance on an enemy over ground that you have not had the opportunity to scout beforehand, for fear of stepping on a high level trap (since lower level traps can be detected in combat).
Now obviously it is not an issue when you have played through the game a couple of times and can recall the trap-laden combat encounters, but for a first playthrough it either encourages save scumming, or the fully defensive "never move foward at all" during combat approach. Does nobody else have an issue with this ?
It seems to me like a big disadvantage to melee focused characters, and a really cheap way of adding difficulty to a game whose various combat mechanics are otherwise very well judged.
