yeah, you've got the ever-present Troon Factor and they're obnoxiously visible, but honestly I'd say, in the ~9 years I've spent playing this game, around 90% of my experiences with other people have been chill, normal, and pleasant. but it's the 10% that always stick in your memory
by comparison, last time I went back to WoW for a lark (mid-Legion), I did not find a single dungeon group where people were affable and friendly like in FFXIV. not a single one, in the entire month I spent playing. every group I joined had this air of barely-tolerant silence until it exploded into people screaming insults at each other because, like, somebody was doing suboptimal DPS or something? it got even worse when I started doing heroic dungeons, it's like nobody is actually having any fun playing that game, I don't remember it being like that before I switched over to FFXIV circa MoP but maybe I've just forgotten how bad WoW is
