Serious Unbalance

I just had a match playing Ezreal mid (middle) lane. This son of a gun playing Yasuo probably one of the msot overpowered pieces of cr*p in the game. First of all, this mother trucker was destroying me. I mean he was fucking going all out, getting me within SECONDS (no exageratiion). meanwhile my FULLLY MAXED Q did a SLIVER of damage to this asstown. How is that fucking balnced? How is it possible for new plyers to have fun with the game when they have to deal with that shit the second match of the day? Makes no sense to me. How am i supposed to compete when my maxed out Ezreal does so little damaged compared to this dude? I have been on and off this game for the past eleven years, taking a seven hour hiatus and i come back to this? Fix your shit blizzard.
