Also, I just thought about this.
In a competitive regional where all the teams play smart and robots perform really well... The best qualifying points you can get from a round is a 66 vs. 64 points... (two robots two goals with 26 balls vs. two robots one goal with 34 balls), which mean a 192 QP... Even the losing alliance could get a great deal of QP's with 64...
(OR a 65 vs 65 tie)
So, I think that teams should work out between each others... Especially since teams know who they are paired up with and who they are going against. Work ahead before the match, arrange that balls robots don't get blocked when they are scoring balls, and leave the goals up to the competitive nature of the game.
Even if not both alliances have ball robots, they should still let the ball robot go around and score balls for both sides. In the qualifying rounds, the whole 2 minutes was a bit long sometimes. So let your opponent go around and score some QP for you. Mean while, you should include scoring for opponents as a big part of your strategy. If you plan it out smart, you can let opponents score while you still win the match.
Yes, you would have to rely on your opponent sometimes with this stragety... So go ahead and have a good talk with your opponent before the matches about this.
There shouldn't be any reason stopping you from working with your opponents. Look at how well 4 teams could work together from last year. Look at the big picture, and don't be afraid to let your opponents score. It will help out in the long way, until finals.
I think it would be really interesting seeing a 66 vs 64, or a 65 vs 65 tie. I can imagine how loud the teams will cheer when that happen.
