This. People only kill Rock because they think Paper and Scissors don’t matter (even though they drop att pots just as much as Rocky does). This leaves the other two free to freak out and find another Rock Construct to protect, which is how we get those huge clouds of constructs that are nigh-impossible to break up.
If you begin with the Wood Construct (the brown one), then the other two will remain perfectly calm and things go much easier.
