Endgame DPS Rogue vs. Monk vs. Ranger

[XeroKill]

If your goal is top DPS, Rogue. End of that story. That is what they do, full stop.

If you want to have a little more utility, one of the best buffs in the game, and a more dynamic role to fill, then really consider Ranger.

If you want to lose XP... like all the damn time, then give Monk a go!

All kidding aside, Rangers can out DPS Monks and even some Rogues, under the right conditions. With a beastly bow, Trueshot and some good RNG (or bad RNG for the Rogues) you can out parse them. Especially when the Rogues are on a bad streak, since their uber DPS is entirely dependent on land their back stabs. I have had strings of 10+ misses in a row, and on those fights, Warriors were out DPSing me. But I have had fights where everything lines up and pulled over 150 DPS.

Lastly, play what you enjoy. There is a place for every class in a raid...except Wizards... don't play Wizards.
