THIS BUG HAS COST ME DOZENS OF LP AND IT'S BEEN HAPPENING FOR MONTHS!

Okay. I don't know if it's only happening to me or it's pretty common, but I have not seen anyone complain about this. Whenever I'm in a queue I accept, choose my declared champion, everything is fine. Not until the bannning starts. The whole fucking client freezes on me whenever I click on the champion I want to ban. Like the whole client literally freezes, I can click on to change my masteries/runes and it shows all the tabs I have, but I can't open the masteries page. Not only that, the whole client teases me to fucking click the BAN button! It doesnt even fucking work! I keep clicking on it till 0 seconds left and then BOOM! I got fucking kicked off the queue and when I check my fucking profile for LP, I LOST 3-10- LP! FUCKING BULLSHIT! Better add this on your new client bug Riot. It wasnt like this when I used to play on the Legacy Client.
