I think that is what made that battle system interesting: More focus on delegation over micro management.
The main portion of the battle played outside of the battles themselves and was all about how you essentially “programmed” these workflows for each character to work in harmony together to win battles. You could get in the fray to fix any unintended outcomes of these flows, but was mainly to observe the outcomes and make adjustments.
I had one of these for years, it grows like crazy if it’s given the space. The branches will get tall and start to droop, then new branches will sprout in to fill in the new overhead space. Otherwise lots of trimming and pruning will expand it also.
