That's nice and all, except every single class in this game is a dps in some way, shape, or form.

Tanks are just beefy blue dps that can take tankbusters without melting like a snowcone on a hot summer day, and have more defensive cooldowns than anyone else. Their responsibilities are making sure enemies aren't running rampant, facing bosses with fat cleaves away from the party, and not eating vuln stacks like candy off the ground.

DPS are DPS, their only responsibilities are not eating aoes like an all you can eat buffet, and executing their rotations with more competency than your average chimpanzee. Any buffs and/or debuffs they make use of should be looked at as a bonus, because a distressingly large amount of DPS players won't even glance at stuff like feint/addle, and getting a summoner to sacrifice their swiftcast to resurrect someone is like pulling a tooth out of a baby.

Healers are of course green DPS, but with a "rotation" so mind numbingly dull it's insulting. Apply dot, spam nuke for 30 seconds, reapply dot, spam nuke for 30 more seconds, repeat until the heat death of the universe. Sure, their primary responsibility is to keep the party alive and kicking, provided said party isn't doing their absolute best to leap into an early grave. But once you're sure they're not going to die within a nanosecond of breaking eye contact from their health bar, then what? Do you just stand there with your thumb plugged firmly up your rear and do some good old fashion Bee's Knee's? Or do you go back to throwing rocks at the enemy like an ornery school kid? If you pick the first option, I will not hesitate to Dragon Kick your rump into the Milky Way, and out of my party.
