I totally agree with this, but sometimes you just don't know that you could be performing better.

As a healer I can easily see when I am twiddling thumbs and could be DPSing, and thus performing better, and when not.
As a DPS I have a problem seeing whether I am performing at the top of my possibilities, it is hard to tell whether it's worth to "waste" GCD for a DoT, or not, when to use GCD for a buff (like heavy thrust), whether it's worth to re-position to maximize a skill's damage, if that means that you will lose a second of doing damage. And so on.

There are many variables in a DPS' game-play. IMO way too many for an average person to keep in mind all the time without using a parser.
