I think we only discuss, and from what I read nobody really want to jump into this boosting star thing right now. Even me.
But in future I'll do it for sure.
I can't resist the possibility of having rainbow Purple Tulip and Purple Pansy in my first 20 girls team.

And if this system not OK, Yo-Game dev will adjust or do something.
Considering that they always monitor everything player done in game.
They will find the way.
