Dude I'm not exactly a casual gamer, and yet I still get my ass kicked by smug hardcore gamers in every single online multiplayer game i play. Among friends, there's a more even and more fun level of difficulty, but online it's a constant steamroll.
I loved shitting on people in CoD and League when I was 11 through 17. Tried to play league now as 25yo and I can see that the noobs that I loved to make fun of just didn't have the time to read guides and study the game 10 hours a day.
Anyway, I get shit on nowdays
