There have been a couple of cases (almost used the word instances in an MMO

lol) and recurring situations that really makes me like the community in-game. Maybe others have similar experiences to share?
One of the things I really like is how players are drawn to each other when questing in the same zone and, without typing a word, group up. This just happens so naturally and I am always grateful for the extra sword, bow or staff at my side. These people will wait for you to finish your conversation with the NPC etc. and then continue together until the quest is done. This may well be a side-product of the vet-content difficulty for many, but a positive one I think.
I have also had the pleasure of trading with other players who are very helpful. One example that stood out was a random person selling me an item, and then running to their guild store to see if the Motif I was also looking for was there. Sure, they probably added something on top, but that's fair and part of commerce lol.
