I agree with the whole "if the saber is off, do not attack!" way of playing. Especially in Duel servers.
The nice thing is that most people who play in Duel know the rules and leave their saber unignited and bow before a match. Then there's the type of players who don't care and try to do the Strong stance at you when you are trying to bow.
One more reason why it is nicer to play on the Zone than the handful of n00bs who play on public servers
