Started playing in late Sept, and it has so far been true in my experience. I have no joke, never once come across a toxic person, and people have been very nice and helpful. At worst, people just don't say anything.
Obviously experiences will differ for each person. No matter what game you play, there will always be morons and aholes.

Sure, people being too nice can be a detriment aswell tho. Like if a guy constantly makes the same mistakes over and over again, you should be able to tell him that he is doing something wrong. You just gotta present it in a good way.
