He doesn't have good enough gear to get in heroic according to lfg so I was trying to do it on regular to finish the quest chain. I got in a group we killed the first 2 bosses easily enough and the shield didn't drop so of course the tank bailed so he could re-queue. a couple of us waited 10 minutes or so, but when we didn't get anyone it fell apart. So I re-queued. I got the same tank with a whole different group. Blow through the first 2 bosses, no shield, he drops group again. Now this time I was with a very patient group. Everyone waited 35 minutes and we didn't get another tank, so everyone said thanks but I've got other things to do. I really appreciated that and they were great we talked about a bunch of stuff while we were waiting, they were a great group. I understand why the tank did it. but I would just like to put this out there. Its only another 10 minutes max, you really could help out everyone else and maybe get some good karma points for yourself towards getting the shield to drop.
