Issue with Hellbowl Dungeon

SO I just played on this dungeon again and realized that for some reason one endzone has 2 easy routes to it (at least 3 wide) while the other side has only one that is 3 wide and the other bottlenecks down to one due to a lava pit and piece of scenery. Kinda unbalanced and gives an advantage to whoever gets that side of the map. Whats up with that and can it be fixed? I can live with the unpredictability, but an obvious advantage to one side is annoying.
