If there was a change I would love to see, it should be fixing the bonus round to get more winners. We had 20 consecutive shows without a BR winner (this was lost in the shuffle due to James Holzhauer), and only ONE winner in May. The show ended the season with another BR shotout.
I think that there are two options: (1) a fourth consonant or (2) the return to 15 seconds. If the contestant(s) brings the Wild Card, he/she/they would get a fifth consonant.
