I would like too see a pressure pad or sensor on the field for the robots. An example would be, that the pad or sensor would light up a light, open a gate to another part of the field

, or move a game piece onto the field for your team during the game. This would make for a good game element that requires teamwork.
The Human player needs to be involved like it has been the past couple of years. Stack Attack was not a good human player game, because they only had ten seconds to place the bins on the field and their effort could be wiped out in the first 5 seconds of autonomous. Triple Play and Aim High are good human player games.
I would like too see the return of a open "bonus" zone. Like the ramp in 2003 or the bar in 2004. The ramps at the other ends of the field make it easier for the teams to go to their own ramps, most of the time, and made some pretty exciting finishes to matches.
