Bungeerace isn't all that lucky, M4dbrat. The bungee is a very flexible item - if you know how to use it. If a certain tactic isn't working, change your tactic. It's all about knowing how to control your momentum, either by increasing it or by purposefully reducing it slightly.
Now, of course there are a couple of maps that suck, but I'm not going to change the rules because of bad maps.
