Most of us have seen them, most of us have experienced them. Let me regale you with a small tale:
No one I knew was on or available last night, so I left my Monk in Druid's Overlook and snagged my shiny Ranger parked in Frost Gate. Now, those of you who have played both know full well the difficulty a Ranger has getting a group over a Monk, so when I found a group almost immediately, I was pretty happy.
I joined the group and it quickly filled. There was me (L14 R/Me), a L11 Necromancer, a W/N of my level, and 3 W/Mo. When the lack of a Monk was discussed I sadly offered to leave, but two of the W/Mo stepped up to the plate and offered to heal while the W/N tanked. 'Excellent. We've already displayed outstanding teamwork skills and a willingness to do what is needed. This should be a slick run,' I thought.
We get in, and hesitant as I am about W/Mo healing, the W/N is pretty sturdy and I do pretty amazing damage with the sparkly gold bow my Monk got for my Ranger. Things died quickly enough the healing Warriors never got overwhelmed. I made sure to heal my cat and myself to keep my load off them.
Problems began to arise shortly, but they're problems I see in most PUGs so I didn't give it much thought. The party occasionally diverged down different paths and there were some passive challenges to the leader (one of the W/Mo) through 'Go this way' drawings and map pinging. The Necromancer had a habit of running off by herself to pick fights we had to bail her out of, and she died twice before we got to the bonus NPC, Rornak (who some people couldn't keep straight with Rurik, hence some odd map pinging when we tried to find Rornak at one point).
Anyway, after some confusion, we realize that we finally found the hidden path to the ballista Rornak needs us to use, but the party is split. A Warrior, the Necro and I are with Rornak on the path when the Necro runs down and aggros about 9 Dwarves and immediately runs back to where the Warrior and I are waiting for the rest of the party. We retreated in short order and let her die...not realizing immediately that Rornak was with her and was killed in the fight as well.

Well, we decide to press on and just finish the main mission, we'll get the bonus another time. The W/N was apparently only there for the bonus and dropped, leaving us short our best tank. Again, we thought we could handle it just fine.
We get the gears and hit two of the mechanisms and figure, 'Well at least we're home free on this one!"
So we are fighting for the last mechanism we need to activate and things are going okay when I decide to loot a white salvage drop between targets. As I do, I aggro a patrol. I am the only person at range and both of them focus on me hard.
I pop Unguent, cycle my dodge skills, and do my best to put them down. By the time I finished one, two people in the main group were dead and I was nearly dead. I didn't even shave off 15% of my second target's health before my beloved kitty, Josie, died, leaving my skills on an 8 second cooldown that proved my undoing.
The rest of the party dropped moments after I did.
So most of us have seen wipes, been present for them, and agitated over the cause of them...but how many of us are willing to admit to having caused one?
