Human players threw the game this year for most teams, except for those with amazing robots (dumpers such as the winning alliance had), so next year I'd like to see something that relies a bit more on the robot itself. People said driving around would be tough this year as well, and it didn't seem like many teams had an advantage over another, aside from being good at pinning, or the "Bump and Dump", as some called it
Also, from what I've seen, spectators get bored by Lunacy, and find it hard to follow.
So overall
Less reliability on human player
More reliability on robot itself
Incorporation of something into the game that makes one element of the robot able to swing the game, instead of the HP**
Make the game easier to follow, and more exciting for spectators
Make the game more interesting and challenging for veteran teams*
*I've seen rookie teams, especially at week one regionals, who have a robot in shambles of wire, wheels, and aluminum, while vet teams had a fully functional bot, but looking at the rookie teams at the championships, they were right up there with the oldest vets, who were sorta disappointed with this years game.
**This year was a year where the HP really stood out in the game, and could easily throw it, depending on the alliance and team itself. It's not necessarily a bad thing, but veteran teams weren't impressed.
