yes it is.   but as was discussed earlier, you...i mean we all love assholes.  or at lesat pounding them.  lol  I think your observations are good.  I too run normally with about only 20% of the group.  I try to be freindly to everyone, and as helpful as possible.  For me WOW is a fun subsitute to chill out with, instead of TV.  so the type of people i hang out with are people i enjoy.  In all honesty there isnt anyone from our guild I wouldn't run with if asked, but I would preferr to run with some over others.  I think that is normal with everyone.
