I would have liked more than one level. Make the first level about 2/2 of what it is, increase the slope, then another level right above that, then suites, then your upper deck, or put suites lower, who cares. Other stadiums are built that way. When I look at Comerica's seating arrangement it is rather dull, especially the lower level. The rows are too long. I really like Busch Stadium and where the Reds play.
The decision about the skyline was also a cost thing ,not just about showcasing the city. The "largest scoreboard" was about cost. Less construction and alas... more ads
They've improved things quite a bit with their subtle changes and Chris Ilitch implied they could do more.
