Human players scoring

[meaubry]

I read the rules but didn't see if the Human players scoring is also limited to "only when the alliance is offense" or can they score when the alliance is also on defense?
I suppose the air will be filled with flying balls at the end of each match as humans will be throwing everything they have before time runs out - and with most teams trying to get on the ramp it will probably be as good a time as any for a clear shot at the corner goals.
Once enough missed balls are scattered about, the probability of not hitting a ball on the ground will be pretty low, but it will be fun to see all those balls flying about.
