An alternative to parsing?

[Moogly]

I'm being carried because I can't clear a dummy?

...that's not a comforting thought to have. :/

That's the whole purpose of DPS checks.
Everybody is doing the mechanics perfectly OK, but the other DPS in the group will have to compensate for your lack of DPS for, e.g, not wipe on the enrage.
"Carried" is a little too much though... Carried would be rather you dying on the very first second of the fight and staying dead while the group is proceeding to clear the boss.
If you do mechanics right, clear the boss, but do not manage to clear the dummy it doesn't mean you were carried : it just means you have room to improve dps wise. As to how much room you can improve will depend on how much HP the dummy has left once the timer is up !
