Same.
Today has been awful as an end user.
Yes quite possibly a victim of its own success, double credits encouraging increased game play, but if the game is unplayable then everyone loses out.
Had a coin sale coincided with the double credits event (or I’d suggest in the 2nd 24 hour of a 48 hour event) there would have been a mass sign up I’m sure, certainly I’d have got my wallet out, but frankly within a few hours of double credits being announced the game was unplayable.
Give us some reassurances, we all know things go wrong but chucking out double credit events doesn’t work if the servers aren’t up to it.
Show us that next time will be better and tell us why and we will all be interested I’m sure, but right now it’s just a frustration. (For us all I’m sure!)
