@justnormalkorean i had a player who kept cheating over and over again and once i talked to him about it he said "fuck it then i won't play."
apparently he didn't find my setting interesting enough or something like that. he didn't cheat in the next campaign my friend ran or the next one i ran, but he certainly looked up the most OP builds that existed in 5e and didn't branch out from that at all. love the guy but man, the way he plays the game is very different from the rest of us lol.
