User blog comment:AraedonMelias/What’s with Oil Rig all the time?/@comment-2052424-20130805025319

It's simple, really. Oil Rig is easy, and requires less effort than most maps. It's a large map with next to no cover. Every time you spawn, you don't need to position yourself, or find enemy positions - right when you spawn the enemy is always right in front of you, right in the opposite room. It's essentially just a larger version of Death Room - it's two rooms connected by 2-3 hallways.

It's not hard at all to do easy on that map, it takes less thought and less effort - small wonder that the map is so adored by so much of the Combat Arms community.
