I grouped with 4 others last night. A Shadowknight, mage, ranger, & druid The Druid announced he was watching TV and may not answer us. The SK thought he knew everything and the Ranger disbanded after the SK got some of us killed.
This was not a good group. Even so I rezzed myself and stuck with them for two hours but in a "safer" area. The result was another level and a half with the SK chain pulling for the ranger and mage pet who finished the mobs off.
So, even in a bad group one can get ahead.... go figure!
