mastery means jack squat
lvl 6 mastery thresh backs lvl 1 after leashing while taking 0 hp while i 1v2 almost win and he gets us both killed. Hits 1 hook the time hes actually in lane otherwise. Makes me miss over 10+ cs laning by trying to targons and misses. For the love of god low elo just play soraka janna and be useful you will win more games instead of losing with a diamond player on your team then blame him for being "boosted" because you suck and belong so much lower elo that a smurf cant carry you in lane since you screwed it that hard LMFAO
moral of the story mastery is just a shiny thing you get that says hi i play this champ. And if you suck it with it its like wow you play the champ that much and still are this bad just stop.
