Reporting players for kicking you will not get you anywhere. The PF leader has always had the right to decide what party layout and can choose to remove someone if they so please. Going back on that would just cause more problems than it would fix.

The real issue is the hive mind mentality that the raiding player base seem to have. The only place where you'll notice Samurai's personal DPS not pulling its weight is O7S, O8S, and ultimate. Outside of those three instances samurai should not be the make or break of the group. Once they buff samurai it should alleviate some of the tension, but it will eventually come back again with another class.
