I accidentally honored them then looked at their match history, they played a large variety of champs in ranked with about 50/50 win lose then started only playing draven/lucian and winning every game with pretty ridiculous scores.
Playing good isnt really a proof for boosting though...

It is actually pretty common for people to be a lot better at particular champs. Check where their flash is tho. People in low rank tend to play more roles and champions.
idk. I used to spam Skarner in every single game possible and then I just spammed Alistar for a couple of days. Without even thinking my entire match history is full of Evelynn games. It could either be booster/ he got bored of those lanes/he got bored of those champions/ he is abusing the broken Draven with DD until it's gone. There could be multiple instances.
