Love the new Client but....

Riot I know that you love your new client and I will admit that some of the animations are amazing and I would love to keep but... its super laggy. The old client never lagged it had glitches though. I know you are still in the beta nad process of building it but if it stays laggy I'd rather keep the old client. I know this isn't really a bug IDK what to call it but I wanted to express my ideas.
