Unlike popular belief CCr has changed the layout of the crag mine portal to aid in defensive situations. The screenshots posted below are from the korean live server, which is currently in episode 2 pt 1.

This is not during a CW this is acutally taken about 3 hours before a CW. As far as i can tell barricades are NOT a player ability, so that was most likely a translation error as they are now part of the map. Also a good thing to note is that AOE Spikes are now Extremely lethal since the enemy is choked through 2 - 3 VERY small holes.
