Games that come to US/EU always ignore EU.
The game servers will be in Germany for EU the log ins will be in US
As they dont care about EU they will fix log in and game servers US side and include us in these times. After all 10am is not a time any of us would play the game (insert sarcasm)
The fact they chose a very poor unattended server company in Germany is why we get very bad lag and server crashes constantly
You get what you pay for
If Germany did its own weekly maintainance it would be about 1-2am too problem is the log ins are in US so they are at parent servers time constraints.
So sadly this is the way of all games that come to US/EU we are just US 51st state the unimportant state :)
Depends on what you class as a work day :)( I only play at work :()
