I honestly didn't care that Med or PD didn't get as much time. As the article stated, it all started with the explosion so it seemed only right that Fire carried it IMO. I'm not a huge fan of med in the first place (only time I watch is during crossover events), and to focus on how Trudy's death would have affected her colleagues would be a horrible subplot to focus on in an already extremely long story line which at times seemed a bit exhausting. Overall, I thought it was a pretty good crossover event.
