Not to be mean. But I guess they found a map where they understand that the easier you play it, the better it goes and just got stuck with it. Now you have a small player base of 3-8 persons? That play it against each other to have 1 strong map. I personally think it's a quite ok map. I just don't like it as home map since it's risky! (To easy to control!)
OR, they just like it! I wont argue against anyones taste
