To be honest, have a feeling most people play on their mobile device. It would be nice to at least add some clothing options (at least different color of shirts, shorts) for both male and female players.
I agree, more avatar options would be nice. Maybe even sleeveless t-shirts for my opponents so I feel like I'm playing at my local NYC muni! Seriously, though, would be nice to have some different clothing options for mobile avatars.
Yeah, and don't forget the soccer cleats.
