I'm tired of losing VS skins

skins make close to no difference in winning.

Skins people tend to do better than non-skins people not because of the skins, but rather because people who tend to be good on champs and have invested a lot of time into it also tend to not mind putting in money for a skin on the champ(s) they're good at.

There's a couple minor exceptions where the skins might arguably provide minor advantages due to the visuals being potentially less clear and/or hitboxes being (purely visually) different, but for the most part the skins themselves provide no benefit.

You (and most readers) probably already knew that, but sometimes inexperienced players might actually have the wrong idea.
