UI Improvement for Lock In
Since the lock in system has a severe penalty, I suggest some sort of UI change to balance it out. Right now, there is no visual indicator that warns the user to lock in besides a pop up box. This is not sufficient at all because many players don't read that carefully. Instead, give the lock in and ban buttons a flashing animation to remind the users visually that they must lock in. Use other attention cue such as sound or hint box pointing towards the button.
