Please don't implement serious changes on Fridays

Look guys, I understand that in the video game world sometimes it feels like things have to be done based on a deadline or some particular benchmark.
At the same time a changed was implemented to the match making system on a Friday when the majority of your staff pushes a button and goes home.
The result is the player base is rather upset, and there is nobody is around to fix what has happened, if it is a bad change.
Please try to do these “Serious” implementations during the middle of the week, so in case of a screw up, it can be fixed instead of people suffering on a holiday weekend.

Agreed. Most software companies stop doing releases on Friday nights, or on the eve of holidays for exactly this reason.
