your winning but you'er not

so like im going like 7/2/2 and wrecking the other team but because the new update with minions and powering it doesnt even matter like what???? so whats the point of doing good when you made a handy cap for those that are bad like i mean like i take 3 towers and a inhib at 13 minutes and normal minions and take on super minions cuz im to high of a level i just don't get it been stuck in silver for like 3 months then i get people that cant even play the game on my team or understand any strategy there just runnning around in jungle not doing anything
