One of my favorite features in fighting games like Street Fighter 6 is the training lab. it lets you drill your mechanics while you sit in queue waiting for your next match. When the match is over you are automatically returned to the training lab.
I love to go into custom games (VAXTA) to practice my aim training, and have seen a dramatic improvement in my ability to aim ever since i started practicing it daily. right now, i manually go create a new custom game lobby while i sit in queue and practice my aim, but i would love to have a feature to automatically return to the custom game while auto requeuing for the next match.
