Parking at Intrust, not a nightmare. Yeah gotta pay $5-$10 to park or park at Lawerence dumont and take a shuttle. It is what it is. But it's the only Venue to hold, imop 4,5,6A. Not big enough to hold all. And let's be real, the stands aren't packed until Finals day, so it's only 1 day that would be tough.
You need to remember, much of that paid parking around Intrust is taken with downtown workers on weekdays. They can't even provide enough parking for the two upper classes alone, as others on here have attested. Trying to add 4A would be a disaster, which I know both Intrust and KSHSAA executives already know.
