The faction war system has one huge flaw.
It's only "fair" when all three factions have about the same player base. At the moment this is not the case. Samurai is really underplayed and are losing because of it. Ubisoft tried to keep people from switching factions by implementing some faction change reward penalties. No one in his right mind would join the samurai right now because first of all they would lose the chance to get end of round reward or end of season reward when they leave after the first round. And they would also be joining a losing team. I think the reward penalties need to be changed. Something like: you do not lose your chance to get rewards when switching from a faction with high playerbase to a faction with a lower playerbase. It wouldnt solve all the problems samurai have now but it would be a start.
