I really hope they are able to figure out some not-too-unnatural way to reduce the likelihood of draws. One easy possibility I saw suggested a number of times would be to remove the increment. Give additional time at certain move thresholds like they do now, but then at some point, that's it. No more time. Time pressure should remain a legitimate possibility of a threat throughout the match. When two GMs are in the endgame, +30s each move is an eternity, and how many tiny moves did we see them make just to get another +30s?

Oh well. I know excitement isn't the main driving force, I just think it's a real shame to see a world championship matchup like Carlsen/Caruana go to 12 straight draws and be decided by tiebreakers.
