After the release of Update 1.14, you may have noticed an increased ping value in the game client during battle.
Why did it happen? With the release of Update 1.14, we performed technical maintenance aimed at improving the quality of the game. At the same time, in addition to network delays, additional time for server processing was added in the ping calculation system (this time wasn’t previously taken into account). As a result of maintenance, the actual connection quality for players remained the same or improved, but the new ping values could cause confusion.
Players are used to determining the connection quality by the already established ping ranges, and we want to keep the comfort they are used to. Therefore, we will bring the visual display of ping back to the previous system in the next server update, while keeping the new optimization mechanisms.
We apologize for the temporary inconvenience.
