OK, I'm at the point where I can say this. It's not worth gimping ANY squad by putting a 3* in it. One more event and I'll be at the point where it's not worth gimping any squad by putting any 4* in it that isn't Lilac. It'd take longer to switch presets around for Secret Gardens and then hope for the 20% chance that that squad is the one to randomly fight the Wealthy Fly and then switch squads back to your original team composition than it would take to just endure the two seconds for the second round of a Fly fight.
