I'm not a new player, but relatively new to MMOs. One thing I've noticed, and become interested in, is the constant preoccupation with the amount of DPS one can generate in battle. Every time you look at a build that's posted on the forums or elsewhere, one of the most important considerations is the amount of DPS that the build can output. I also sense that there is two types: Sustained DPS and burst DPS.
I'm wondering what is the best way to measure this? Do you look at one single ability, or do you arrange abilities in a certain way to maximize your output? Which is more important, sustained DPS or burst? Do you clock DPS over the course of a battle, or do you measure DPS from a single attack?
