Ability vs Gear

I was in queue and got into zul grub random. They were on the second boss so I didn't think anything of it at the time, but sometimes its a bad sign. We started the fight and it was going OK but it was going very very very slowly. Rezzing ghosts ran out, people started to die(boss move, not me), and then we wiped. Boss didn't go into enrage phase, well WTF? As I checked the damage done meter, only one player was pulling their weight doing 10k while the three were doing 5k each. No wonder what happen. Just because you are able to queue for these dungeons with a ilvl of 346 doesn't mean you should be doing them. If you have the gear and your dps is low, figure out how to play your character! Even if you don't research it, play with the dummies in the main cities and see how you can raise your dps. It takes the fun out of playing when others expect to be carried by others. The worst thing about my situation was the three that were doing 5k each were from the same guild...
