Just from being at the Arizona and LA regionals, I can tell you that the winning alliance has at least 2 robots that can pick up from the ground. From there, I'd also state that a winning alliance only has high (exit point) shooters, except for the ones that get on the ramp and do that whole deal. 2 shooters isn't exactly necessary (968 proved that in LA) but I think that you need at least a shooting robot that has a high point per game average. Then of course the dumping bot that also is good at defense.

Basically I'd say, the best strategy is to have a defensive robot (maybe it can also dump), a very competent shooter bot (high point average), and just one well rounded robot that can switch off between shooting, dumping, and defense.
