I just happened to get my hand on the new client, and even with the chat currently being disabled due to errors I still find myself really in awe of the design choice they have decided to go in.
**Flaws so far: **
So far I have found to enjoy auto locking in 5/5 on masterys on the old client and found when fiddling around with the new mastery system I had to manually enter each point and the animations were still a bit dodgy. Secondly I didn't see much in a way of ranked teams information on my profile (there's currently a drop down menu but not much on stats yet, probably still in the works so I will forgive)
Some of the images in the store were stretched tremendously due to the old client as well.
**Praise so far:**
So far I've come to love the new champion select -- the backbones are there while some of the animations are still to be implemented as shown in red posts, and by lord the animations teased are amazing I cannot wait.
Loving the sound effects for banning champs so far (would love if kech would say something about "benching the kench" though)
**Review score:** So far as it is still in alpha I cannot give it a high score as there is still a lot to be implemented into the client. I hope my feedback is usefull to you riot.
_I give it a solid 6/10 for effort. --- Your friend Toxxsii._
