I read somewhere that the daysingame displayed are wrong, the website tells the truth... so 7 days left should be more correct, since the website says until july 7. (also somewhere in this forum is an official statement that the countdown ingame is incorrect).
Since there is already a thread discussing the even length of Midyear Mayhem, we are going to go ahead and close this discussion. Thank you for your understanding and we hope you will continue the discussion here.
