I'll admit that I'm new to FFXIV as I've only been playing for about a month, but this is on the heels of having played WoW for 15+ years, so I have 2 cents to toss in real quick:

In my experience, toxicity can be present on both fronts, both from folks who want to hide from their mistakes and those wanting to force their opinions on how the game "should" be played down other players' throats.

For WoW, the greatest toxicity came up during endgame group content, namely M+ and Raids. And it is RAMPANT to the point that I finally decided to quit that game recently. It's frightening how many folks are so incredibly focused on completing endgame content and treat it like a job, and are all too happy to mutilate other players in the name of accomplishing that goal.

From what I can tell, the makes of FFXIV are actively trying to avoid that problem. And honestly, I applaud them for that! Like I said, I left the other game because not only did the makers there not do anything about that kind of self-serving attitude, they actively encourage it in how they design the game. And it's making the game worse for it, which in turn is causing more and more players to -not- want to play endgame content.

I get not wanting to have to spend extra time to work with others to improve, but conversely, that's part of being a multi-player game. Remember that other folks are paying to play this game as well, that nobody would have the world to enjoy if everyone wasn't participating. I feel it's better to air on the side of caution and be gentle with folks and make efforts to help rather than resorting to blunt tactics and force in order to strong-arm self-serving desires.
