Just more shitty game design from the shitty game designers. Support class doing top dps (and also buffing party damage) while the dps class that has no mobility, utility or defense, just damage, is almost at the bottom. Because chanter's stuff is all front loaded and assassin is the opposite, for "reasons." Eventually it'll swing around and chanters will only out-dps clerics. But, will assassins be top dog? Nope, brawlers. They'll probably have more survivability, too.
Also, sins have to try to stick to the backs of bosses that ignore every law of physics while hitting a bunch of buttons to create dps spikes, while chanters just toggle on buffs and hold down macro...
