There are plenty of things that could be done to improve atmosphere with only minor upgrades to the exterior areas. Fix up the fountains, put up statues of the real sports heroes (Stieb, Carter, Bautista) instead of cable tycoons, and put in street-facing retail (remember the McDonald’s?). The beer selection is even worse now than it was a few years ago, and that should be fixed.
Places to congregate right outside the stadium will help, definitely. But the interior renovations are pretty good, and the complaining is tiresome.
