if there's no moshing there won't be atmosphere lah, but of course too violent is damn extra, like when plainsunset did one emo part then some jokers went and body surf, that was retarded. There was a point when i saw one girl behind me that just came out of the pit, she was delirious, not knowing what was happening. and i saw one guy being carried out of the pit, obviously he had fainted. There's always these risks involved.
but, i'm one of the guys at the back. so, its cool 8)
