I'm a sucker for a person saying "hello!" at the beginning, "gg thanks!" at the end, and not being a douche. I don't know - I think that's the intent of the system. To encourage people to be friendlier.
Agree with this, much of the fun clearing stuff is about having fun with people who appreciate, not those who play like bots, seek loot, currency, then onto next dungeon. Big part of MMOs is about community and overall experience while progressing.
