Players do. I don't know if I'm just unlucky or if this is what you meet around every corner but I genuinely meet only toxic players, gankers, ledgers. They are absolutely delusional
For example:
I picked up Conqueror for the time being until Testing Grounds comes out and I'm okay-ish at him. Was fighting an Aramusha and I was winning by using full block stance in his combos, at the end he was 1 hp and he was turtling really hard. I bashed him once and kill him. Then suddenly him and his mate jump at my throat by calling me a bash spammer, ganking me the next round
Another time I was playing Cent, being an honorable opponent, waiting for my team mate to finish his 1v1. He loses but I turn the tide and win the round. Suddenly next round I find myself in a Stampede Charge in front of a ledge because ''Centurion is for noobs kys''
Some players just cannot take the L, whenever I lose I am respectful towards the opponent and drop a ''Good Fight!'' or when I see a really good Valk or PK player I usually congratulate them in all chat and I acknowledge the skill that they possess
