Well. there goes my hexetech dream.
I decided to play support for the first time in a while, locked in Nami, had an Ashe ADC, so we've got cc and kiting for days, all good. Coming out of Laning I'm 4/0/5, feeling pretty good, now, I got caught out warding and we lost a fight at dragon, but all in all, I'm having a great game at 4/7/20, wonder what mastery level I'm going to get, guessing like A or B+, get into end screen and little orange blurb shows up "you cannot receive mastery chest if you do not own the champion."
Damn you free to play, damn you.
