If I'm pulling way more DPS than I should be and we keep wiping, I'm out. It doesn't happen often though as most dungeons can be carried.

With randoms, if they do like 5k dps in a vet dungeon, I leave and tell them why if I'm not playing a DD on one of the easier ones and can carry them quickly. Otherwise, number of wipes or time is less important as long as I see we have a chance. People did give me a chance to practice when I was new at these things, and I like to return that favor. You can always port out to repair.

I don't leave guildmates unless I have to. Spent 6 hours doing vICP first time with some guildmates who hadn't done it before either. Spent many hours trying to clear nHoF when it came out, though the guild stuck to 2-3 hours sessions at a time to maintain our sanity.

When it becomes clear it is not possible to beat the content, or it will take a significantly longer time than normal to do so with the current group.

I leave teams when either im bad for the group, the group is bad for me, or when we complete the activity.

1-3 wipes. Depends on my mood and overall feeling of group strength. Good to be healer, no need to worry about queuing time.

I have never left a group but I, mostly, group with my friends.

I leave a group whenever I want to. Nobody owns my time but me.

In 4-man groups I will leave after a few wipes if the players are obstinent. If they are noobs but willing to learn I will try to train them and keep trying as long as I have time and they are willing. At that point, it's less about completing the dungeon quickly and more about helping others get better at the game.

In trials, I'll leave if the raid leader is a jerk or if the group is obviously hopeless.

If they refuse to learn mechanics or play as a group. Why would I bother then.

When people send me messages about my play when I play a healer exclusively and I'm not the reason people are dying.

I tend to do dungeons, and I'm one of those who is happy to help new players through dungeons, check whether they need to stop to do quests, and generally make sure they are ok and having fun.

So I don't normally leave dungeon groups unless we wipe multiple times on a boss and the group makeup clearly isn't working.

I did have an incident in Cyro recently though, I was in a campaign with a pre-formed small group, we had some things we wanted to do. A random was invited to group, and was quite pushy about what s/he wanted to do, which is not what I would have decided to do, or in the way I would have chosen to do it, with plenty of moaning about "I normally lead groups, not join them" - so as I like to keep people happy, I handed them the crown then left group and reformed with my friends so that we could do other stuff.

Yes it might seem petty but I was there to have fun with friends, not be bossed around by some random (who had a much lower PvP rank than I do and was IMO 'doing it wrong').

Only if people are absolute jerks for no reason. I love helping people learn if they don't know what's going on, and I'm patient if group DPS is low, as long as the people are pleasant. There is nothing better at souring an experience like horrible, negative people.

Pvp? When the group leader does not know what he is doing.

Pve? Never. Since i do random normal only i can carry the group alone even if the others are terribad

When it's done. I will finish the dungeon I join, with or without my team.
