Multiple uniforms/logos you can easily switch up. Would be nice to have dedicated uniforms for theme teams.
Id be happy with customizable sleeve patches and some more letter/number fonts. With the exception of 1 or 2 styles, i think most of them are hideous.
I just wanna give my team actual MLB uniforms, which seems to be too much to ask.
another idea for 21....servers that are stable enough to not kick people in the middle of a game and support staff who don't trt to pin it on your ISP when there is a problem
