We are sorry for your confusion that we've caused. There're 2 different servers in game, which are generally used in 2 different ways.
In the lobby page, you can see the Battle Server icon at the top of left corner and the Lobby Server icon at the top of right corner.

1. The Battle Server provides us with exciting gameplay experience while playing in the battlefield, so the ping of it is particularly important. We sincerely suggest you to select the optimal server (which has the lowest ping) before you start a match.
2. The Lobby Server provides us with many fundamental requirements in game when we are not in a match, like Chat, Inventory system, Missions and Clan system, etc. So the ping of it doesn't mean the ping you will encounter in the match. We would like to inform you that you don't need to worry too much about the Lobby Server ping. It's normal when you see the icon is yellow/green, which means the ping is under 200ms or 100ms and it will not cause any bad influence to your matches.
