I've had enough with these bullshit impossible to play champs

I got Azir from mystery champ, and I have to say I am more disappointed than a kid who got just a chocolate cake and 10 bucks for his birthday. I CANT PLAY HIM. HE'S THE HARDEST CHAMP I'VE EVER PLAYED. After every game I play as him, I feel like I wasted time. Most of the time, after a long game with a certain champ, I feel good that i got slightly better at said champ. Azir is not this way. Every game I feel like I accomplished literally nothing productive. His q pisses me off because the range is so low it might as well be a melee range ability, his ult literally never works for me, it never knocks anyone up or anything, and all it does is force the enemy team to walk around it, which is just like a 1 second difference. I've only won 2 games, and that was because I was fortunate enough to have teammates to carry my sorry ass.
