I played with this mastery 7 
. Only to find out he's being boosted till mastery 7. When my team caught him being bad at him as he kept running down all lanes, doesn't know how 's combo works then feeding on purpose. Then lastly being toxic and shifting the blame on us for losing his lane.
OK. what's your thoughts about this fun fact?
There is always a chance that a champion with mastery 7 is being boosted as the account might be played by another good player with that champion in order to boost it till mastery 7 then gave back to the original yet less experienced player. You supposed to be experienced with that champion yet you perform so poorly and doesn't even know the combo well which makes you being suspected being boosted.
You do not have to be good at a champion to get mastery level 7.
I have mastery 7 on 
despite being terrible at him, high cs and few deaths are all it takes.
What makes you think Mastery Coordinates with skill/experience? It doesn't even accurately depict how long you've spent on a champion that is pre-mastery system.
I would be level 7 Mastery on so many more champions then i currently am right now if the system was released when i started playing, i could pick quite a few champions that are easily in my top 20 ( i own them all ) and you would have no idea, because i haven't been playing them consistently since Mastery came out.
It's true. I'm 1 token away from mastery 7 on GP and I can't land barrels worth a damn
Mastery doesn't communicate skill, it communicates games played. Still, I don't know why this matters. You don't find out their mastery until the loading screen, and it sounds like this guy is trolling.
You're posting like you were aggrieved.
