Feedback Regarding Subs
This hasn't happened to me yet, but it has happened to the players in my league. When a substitution is made, the person who has the player being subbed misses out on potentially game winning/losing points (example: Meteos being switched out for Inori between game 1 and 2).
An easy fix to this would be to draft positions on a team instead of the players. One could argue that there's some strategy involved in deciding who to use, but subs can happen out of nowhere between games without being able to plan for it which can basically lose someone the game. Along with this, I would include pictures of both people on the position to make it clear that you're getting both. Hope this becomes a thing, but this section doesn't seem to get a lot of attention.
