So... there are flocks of people across multiple servers in (from what I have been reliably informed) multiple countries that are experiencing lag so bad that they feel the game is (almost) unplayable and somebody at Blue Byte thinks this is a good time to try and hawk some gems... really?
A word to the wise: It's kinda hard to convince people to spend money on a product they can't use properly.
Now is not the time to be trying to flog your wares... now is the time to be doing whatever it takes to make sure you fix the problems you created last week by this week's maintenance at the very latest, followed by much public grovelling and some freebie premium time for those people who have been unable to use the time they had already activated before this week of hell!
