Honestly, it could be asshattery or there could be more to the story. I have left groups before for another, but only in extreme circumstances. For instance, if the group was just really not going well. And by not going well I mean being in fear for my "life" on just about every pull.

In fact, I left a solb group last night not long after joining it because several friends of mine logged on and wanted to do something. I apologized to my group, helped them clear the next few rough pulls and clear to entrance, then headed out to hang out with my friends in guk. Hopefully no one considered this to be asshattery. I feel like I got better exp with my friends, mostly because we group often and work fairly well together, so technically I did leave my group for better exp elsewhere. However, I didn't leave them tankless, which is a bit more serious.

So my take... yeah, sometimes it is asshattery, but don't be too quick to judge someone after only one circumstance. And please don't be too wary about grouping with people from top guilds. Sure, you'll find jerks, but you'll also find a lot of really great people. And I'd wager you find more of the great people than the jerks.
