Riot, fix your game
So the "new champion select" dropped today, and I can see why Riot got rid of team builder. Problem is, they set it back to the old system because of a bug. And guess what? THE OLD SYSTEM IS ALSO BUGGED!! I'm not sure what the bug was on the new champion select because I haven't encountered it, but I have encountered a bug TWICE since they switched it over. I've played 3 games, and in those 3 games every time I have switched summoner spells. Two of the times, after I switched summoner spells, I couldn't interact with the champ select at all! I couldn't click on the window! and both times, I hadn't changed anything by way of masteries or selected a champion because I always do the summoner spells first, so both times I've had to dodge and take a penalty. So, either remove the leaver penalty until the bug is fixed or set it all the way back to the old, NOT buggy system until there are no bugs in the current system.
Also, the PBE exists to ensure that bugs like these won't get into live, so every time you get a bug report from the PBE, fix it then put the new version on the PBE and see if you start getting more bug reports. If you do, fix that bug, and then repeat the process until you aren't getting these bug reports. And stop releasing OP champions then dropping several patches worth of nerfs on them, listen to the feedback of the PBE players. And anyone looking to queue up, I guess until Riot fixes THIS bug, always switch your summoner's spells last and only switch one unless you don't encounter the bug. 2/3 games of this bug happening is just too big of a ratio.
