I end up making quite a few PUG runs, in addition to dungeon runs with other members of Gaiscioch. Earlier today, Balor was leading us through AC Explorable, Path 2. We got to a point where we couldn't proceed. In the room where the NPC fixes the cannons, we had a final cannon with 8 mobs around it. A couple necros, a couple elementalists, at least one monk, a couple warriors. Something like that. Anyway, we tried various strategies and it took a whlie, but in the end it was clear we couldn't finish it.
In a lot of the PUG groups I'm in, as soon as things start to go wrong you get at least one and sometimes multiple players throwing fits in party chat, ridiculing people, and generally behaving like infants. In our group this morning, everyone was cool, relaxed, and having a nice time. We didn't succeed in the dungeon, but it was a good time and as always a good group of people to play with.
