We are announcing today that the physical EU servers will be integrated to DE region, which will make the server time on the EU servers is changing to Central European Time(GMT+1). This means that existing events will also be held according to the CET time, so be aware of this before playing.
Regarding the server integration, please note that each country/language server will be maintained and you shouldn't see any difference in your gameplay. So please rest assured, you'll be able to play as usual.
We will do our best to ensure a smooth gaming experience on these servers.
