one of the weirdest things about persona 3 is that fusion isn't commutative, (persona a + persona b) will have different abilities than (persona b + persona a)
@bea probably, but i think in this circumstance it's a big usability issue since it means you have to check all possible combinations of personas for every fusion, which is annoying, especially with triangle spreads
@lycaon commutativity is overrated anyway
