is writing out a ticket to report a booster worth it?

so i had an obvious booster in my game,the guys plays tryn/yi top jungle in his whole match history then the past 6 games just out of the blue plays ap midlaners with extremely good kda's for someone whos never or barely played mid. Normally i wouldn't care and just move onto the next game but they were just being arrogant in all chat so i wanted to report it to riot... but is it even worth the effort.... how likely is anything to even happen?
