however they can give DPS a realistic idea of how close they are to an "appropriate" level of damage output. If you plan to tackle "high end" content you should be able to maintain your rotation with minor interruptions.

SSS allows you to check whether your gear and rotation is enough for the content: Didn't pass = Need better gear/rotation, Barely passed = You need to tweak something , get buffs or improve gear, Passed with spare time = You're ready to try and clear.
