I think you get coins, but I'm not sure what those coins are used for.That still doesn't defeat the purpose of battling. If someone wants to be even stronger, they can battle more. If you felt strong enough, that was your choice to not battle.
In comparison, there is no point to battling in Origami King. You get nothing.
So any game that doesn't have experience, you're saying battling is pointless? Interesting...
