I ALWAYS assume that unless you have a skin, you'll do badly if you're using a free champwhy?because them being free allows the idiot general public to use them, and then go 1/8/5 as support oriannnahoweversince you wouldn't(and can't) buy skins for champs you don't own, having a skin is sort of like a seal of quality for free champs ensuring that the diana will get fed and burst you to death repeatedly
Only if they are using a hypercarry like Jax.
I remember when xerath was free last week. Most of them fed since they couldn't combo or anchored themselves at the wrong time.
I believe that everyone will do badly, regardless of skin or free champ.
I only play with champions I own, but I do not own skins for all the champions I own.
I usually worry when I see the free champs being used on first couple days of the free week.
You are not allowed to request a sticky.
