Climbing is already enabled on Dunwarren WEST Gate. However, attempt to climb the Dunwarren EAST Gate towers will result in the too dangerous terrain message. Given the dangerous nature of the area, climbing would give a temporary relief to cornered people.
Adjusted for next reset.
The far end of the the Dunwarren East Gate still gives the "too dangerous" message. Didn't get to test the near end of the Dunwarren East Gate though.
