I played the game on CN server before, and it was much better than AoV, although they are basically the same game.
The gameplay itself is great, no wards needed, items and be bought instantly so the game is much shorter, the pace is faster comparing with Wild Rift.
The animation and graphics are great. I turned off the sound when I played so I cannot say anything about the sound.
The matchmaking and anticheat system was great. I barely got any trolls in my games. However, below gold division you can only match with bots so me and my friends got bored easily.
The only problem I got was ping as I played from outside CN server and had to turn on VPN so it's pretty laggy. I hope in global server this won't be a serious problem.
