I used to play World of Warcraft and World of Tanks... I just can't deal with people in games any more.
Even when I play MMORPG I tend to avoid people. I only interact with people when I have to do a dungeon or quest. I'm a bad MMO player tbh.
I play FFXIV and used to play Blade and Soul. Dabbled in WoW, but didn't take to it. In terms of people, I love the social element of MMOs. It's really cool to sit down with people in a guild you've been playing with and hear about the cool things some of them do for work, swap stories, or just chat about the game. One of the reasons I quit Overwatch was the community, though, so I know why some people just choose not to interact. I love team games and I couldn't find a consistent group of people to run with who didn't lose their shit in Arcade mode.
