Amazing map, one of my favourites now.

But is the electric cable separating the spawn from the middle of the map really necessary? Too many times, I've been chased by zombies and backed up too far in that direction, and ended up dying by electrocution before I could figure out what happened. This makes the beginning of the map really frustrating, especialy when playing solo. Can't there just be a regular solid barricade separating the two areas?
