Change, back, this was a mistake

When the new client was announce I was in love with the idea of it seeing as the old one had quite a few issues. NOW that the new client is here all I have to say is: roll back. This new client is ridiculously laggy, not just for me but also many people I know, you can't adjust masteries in the lock in screen anymore because of how slow it is and sometimes it glitches saying you don't have enough points on that tree even though it clearly shows you do. Also its now been at least 5 games in the last week that I get kicked out of the queue because I "didn't accept", the thing is: I did, infact I spam the accept button but very often it refuses to respond.

I'm sorry it looks great and it was an amazing idea but... go back to the old one and fix this, this is bad even for a beta seeing as players are being "punished" just beacause the cliet won't co-operate. :c
