I recently went on holiday and tried to PVP 10-15 times and at first there was just a lot of lag and I couldn't cast many or any skills, but after the 3rd or 4th fight I simply disconnected instantly or just watched a static screen for a minute. The WiFi was fine, around 10mb and the connection was stable, even tried using Skyroam which was a lot better in terms of connection but the game always disconnected. The game is awful on Mobiles. You need to play on a computer using Blue Stacks or similar, but that isn't perfect as that program can crash too.
