Just a normal game and I want to have some fun. But it made me really confused. Who can tell me what I did wrong ? My teammates keep telling about somethings like "You take all the cs and all the kill, even not let anyone assist" "GG cait, you cannot 1v5" "So how to be the alone carry?" I really didnt understand them at all. Are people here want everyone must equal? Play better than others should be blame, its true?
