There are two attacks in this game up and down with a bayonet, therefore dueling is fundamentally flawed as there is no way for 2 competent players to consistently out play one another with only 2 variables. Kicks, chambers/block-chambers etc, can easily be either dodged out manoeuvred or blocked. So duels come down to one of the two players making a mistake ending in one of them to die. In NA you can argue that the "fastest" speed allows this to happen more quickly. However in EU we have already transcended beyond this and players such as Hokej and Ledger have the patientce and competence in dueling to not make mistakes for such a long period of time that duels last stupid amounts of time, no NA players have reached this level of competence in melee yet and therefore have not experinced such long duels. Additionally their meta melee style is different to ours and they decide rather than winning the duels, reside to spam eachother, go for risky chambers and kicks and make many mistakes resulting in more people winning in duels quicker. Overall it seems Eu's have dueled enough to understand that the system is flawed and Na's are yet to discover this and are still spamming like children.
