I saw suctions cups used several times with mixed results. when they worked, which was more often then not, they worked well.

Stacking is just patently inefficient, because it takes many seconds to build one and virtually no time to knock it down. So far the best strategy seems to have been to let your human players build a stack and then just to defend that.

It looks like the general consensus is that no stackers can stack efficiently. Well, you could be right, however, I feel that the team that wins nationals will be comprised of one VERY efficient stacker and a ramp blocker/KOH. I really feel that the team everyone watches will be the one that stacks well. I could be wrong about my presumption that one of the say... 1200 bots across the nation will actually be able to stack, but I feel that everyone, including those who are skeptical will be impressed at the sight of a stack of 8 or so. I would love to see it whether they are part of my alliance or another.

Either way, I think at least one team will wow everyone with their stacker
