Okay class... Let's look at DPS from a different angle today:
"DPS is for closers."
Do you think DPS is a 'carry-me' role? You do? Hahahaha... Then I have news for you... It's an important role that must be respected and ...
earned.

You just won't cut it by going cross-eyed with your tongue sticking out, while wearing your pants on your head, and using your nose to repeatedly hit one button like you used to ... in some other MMO.
Ask yourself: have you earned the privilege to DPS today? Have you healed successfully, and kept/got every one up? Did you tank it like a champ, and made a chump of the boss? Yes? Good. Then you have earned the right to try your hand at the highly coveted role of DPS!
Since you have either played a critical supporting role, or you were the main attraction, then ... you likely would have learned how to use your skills to their fullest, but equally as important, also learned the mechanics of the fight (as in, when to use what and how). Furthermore, you likely would have been accomplished enough with your ultra-sneaky super-ninja button-mashing '-no-jutsu' skills ... to discover the awesome magical world of ... *gasp* ...rotations. Wheeeee... :P Yay! High-five for "rotations!"

They are SUPER Effective for DDers btw.
Now, before you get your coffee and cue-up as your favorite DPS, hit that practice dummy some rounds and learn how to dot it up, buff u up and fire your DD CDs on cooldown, while rolling your rotation like a pro! Got that down? Awesome! ...And who's awesome? You're awesome, for making the effort to put your best foot forward before you queue up!
Now get in there and show everyone how to rock a DPS!
