A lot of the time, it's hard to blame one single person. I will say I've caused very little amount of wipes though, just like I'm sure there are many healers/DPS who can say the say thing. Why? Research.

It's a very big, very open MMO title. I read up on dungeons before I go in there so I know what to expect etc. The same way I know where to aim next for my equipment upgrade. I don't understand how any player thinks they can wander into an MMO and know nothing about what they're doing and do no research.

Worse, when you do have suggestions, people can be so abusive. I got called a c*nt in a group the other day for saying 'What's causing the wipe? Is it a case of low DPS?', met with an abusive response from a black mage. Vote to kick, and it was a unanimous decision. So general people skills also help.

I'm finding now I'm at endgame and doing harder dungeons, I'm suffering the misfortune of playing with these kinds of people much less than when I wasn't at level cap.
