I was very happy with my presale tickets this time around -- I had front row, close to center. But a couple of years ago I got presale and ended up with 6th row...waaaaaaaaay off to the side. They were terrible seats.
I agree the ticket limit should be about 4. Also, presale seats shouldn't include seats (front row or not) that are way off to the sides. I noticed some people in the front row were sitting in front of the amps. I would rather have seats further back and center than off to the side.
