I agree with nicksang 100%. While I don't think every set needs the full 40-man roster, I don't mind seeing one per year. As a team collector, and also a fan who watches my team almost every night, it would assure me that I could get a card of every player on the team, in a Cardinals uniform, and I'm sure other team collectors would feel the same way about their teams. I can get a ton of Yadier Molina cards in a Cardinals uniform, but Seth Maness didn't have one single card in 2014, and almost got missed in 2015 too. (Thanks Topps Update!) And he had a combined 149 relief appearances in those two years. Sure, a Padres fan wouldn't likely care, but I want to be able to have at least one Seth Maness card every year. He's a VERY important part of our team!
I'm going to reevaluate how I collect after the new year. It's just getting way too expensive for the new stuff. Sometimes I just want to buy a pack, not a whole box or even blaster.
