All The Bugs

so many shit going wrong.

1. We cant play on the game modes on the new client
2. The Mastery page is bugging out where it wont let me change my masteries and the only fix is for me to logout then log back in
3. The new client is very laggy at times
4. Why cant i play on the old client (ive uninstalled and reinstall to try go back to the old one always goes back to the new client)
5. There is no way of looking at the new items besides a internet search or in game or looking at any item in general
