First I love Gears of War Saga, and I'm an achievement hunter! So, it's really anoying that 1 achievement is impossible to obtain!!! In the particular case of Gears of War: Judgment there is an achievement called "Sybarite" and in order to unlocked  the gamer needs to play 30 events from the multiplayer, BUT there's been a long time since the developers have updated the events so now it's impossible to get for us! IF the developers are too busy with the new game, then... why did you created an achievement as anoying as this one! It's not our fault that we couldn't play the events when they were online! so I'm asking PLEASE fix this problem, WE understand that you are busy but, you should understand us! We love achievements and we can't stand an achievement impossible to get! maybe you can created 1 event daily or maybe you can give us the achievement when we enter the multiplayer (as you did with Gear of War 3) 

so please fix the problem, and don't make another achievement as this one for the next Gears of War game! Thanks for reading
