Bronze players who got boosted to Gold and Plat...

What are everybodies thoughts about boosting. Imagine, some plat or diamond guy played on a bronze player who most likely says "I'm better than bronze, my teammates suck and are all horrible I deserve Gold at the least" Gets Gold because of boosting... Then you get that guy on your team.

I say this because I've seen these players become more increasingly apparent. That mid laner who makes 40 cs in 15 minutes... The guy who says "I can't support, I'll take jax bot"

Then you get in game and you see them do some of the most awful things. For example, you have your top laner and he gets caught out (It happens to us) but theres obviously 5 there. Then your jungler for some reason tp's in to try to 2v5...

Can't riot crack down on these guys?

Also are there many diamond players that were carried up?

Also a note for everybody, what league you're in is where you belong. If you sit around 50-55% win rate you belong in your current league. It's not because of teammates. It's you. I'm Gold, I cycle between Gold 4 and 3. If I was a plat player (Like a lot of golds believe they are) then they would beable to make it to plat.
