I feel I can make a pretty coll uniform with what's given. A few more options and stuff would be cool but I've made some cool uniforms. I do wish I could use my club jersey as my drop jersey.. although they would have to ensure away jerseys are either white or a light gray for their base color.
Goalie helmets could/ should be possible even if we were only given 20 or so patterns to customize.
I would agree about custom logis but they've shown they aren't willing to even look at team rankings to get rid of clubs with inappropriate names. They certainly aren't gonna make sure custom logos are appropriate for thousands of teams. If you had some cretiria like get club to max prestige or something so there were far less to go through it could be possible. If that were to happen it would be cool if your club could have that logo tethered.
