OMG gen speed
Just wanted to post this before anyone else does. Since this seems to be a trend now.
But no, I don't think gen speed is in anyway a problem. Once again, you can't increase objective time without just breaking half your game balance wise. It just wouldn't work. Just imagine Nurse, Spirit or Hillbilly with increased objective time.
This right here, if anything, is a Clown problem. And maybe a map problem.
