Group time commitments ?

[Seeatee]

I was just wondering, when going LFG or the reverse finding a player to fill a spot in a group what are the expected time commitments, obviously it would annoy some people if they were seeking a cleric for 45 minutes they find one and they leave after 10 minutes in group.

I am leveling a couple different tank chars, and I feel like if I spend any less than 2 - 3 hours in a group I am cheating them, would it be acceptable as a tank to go LFG and join a group for an hour of exp time then leave? does the camp matter? a camp close to the zone line that is easy to access not as bad as a camp that's deep in the zone and takes 10 minutes to clear into and out of?

just wondering what everyone's opinions and views on this was.
