These problems suggested are menu navigation/QOL problems.
(Quality of life Issue)
When you navigate the fighters ability detailscreen, it would be nice just to switch between characters by klicking left or right without closing down the detailscreen. Less clicks are always preferable.
Once you complete a part in the tutorial and goes to the reward screen, there's a small time-span between when you can navigate the continuation options and when the loading is finished. I would suggest you show the continuation options once the loading is finished so you don't confuse the player and risk him/her from klickning around unnecessarily.
(Moderate issue) (Xbox one)
The chatt function in the end of a game is very poor. Slow, unresponsive and frustrating.
Also make it possible to chatt when rea'spawning. Also xbox.
