I'd say, if there was absolutly NO WAY of camping on the starting sides, I would like it. The fact that only with a little portion of brain anyone can stop there and camp it while almost everyone jumps to their death....
think of 2 persons on different sides decide to camp it up there, and someone is left at the bottom... everyone would have to wait 8 mins because they all decided to wait there (since most likely, those 3 would vote "no" to any map vote)
