you can't report me for picking shaco!

Yes I can and I will. :)

They can actually report you for whatever they want. But if it is frivolous, don't worry about it.

Also, 100% of people that say "shut up kid" are kids.

Yeah people can. But people who report others for not playing the way they want them to are idiots.

lol shaco is a trollpick ofc i report him

If this is more than sarcasm, my thoughts are here.

You sound like you care more about winning than enjoying the game now. I know that winning makes the game more fun, but not when you prioritise it above everything else. Maybe take a break from League, then you'll enjoy it much more again :)
