Client Bugs

Answer me this Riot. Why do you release new things to the live server if they are still broken? I was just in a ranked champion select and I was changing my masteries and the mastery page graphics would not update. I would click on one and it would say there are points in it but no sound would play and the box would still be grayed out. I literally had to dodge the champ select because I didn't want to cost the game by taking the wrong keystone or not having a keystone at all. (Also earlier I clicked on the button after a game to re-queue and it literally made the top of the client empty space, like the top 20% of the client was void.) Could you guys do some more testing or leave it on the PBE longer with new things until all the client/game breaking bugs are ironed out? I'm actually (like a lot of things in LoL) preferring the old version MUCH more then the new version.

Mastery page bug steps: 1- Queue up for ranked flex. 2- Accept champ select 3- Call champion (Tristana) 4- Open mastery pages. 5- Broken. No top bar bug steps: 1- Enter game. 2- Finish game from remake. 3- Click re-queue 4- Top bar gone.
