Please consider refreshing opponents when kisses are earned. At my level, I have to wait until I have accumulated 10 kisses so my relative mojo is lower before battling opponents. However, after several battles, as my mojo increases, my opponents are all too powerful. Most of the time, if I refresh, all three are still too strong. I have to have patience, until the the pool of higher-level opponents have increased their mojo, making it more likely my next opponents will include one I can beat. However, even after waiting several hours, I still face the same high-level opponents until I refresh. It would be nice if they would refresh periodically, without having to spend kobans.
As long as I can advance 1.5 tiers every day, I'll be able to claim all the rewards, but it is very tedious, and so discouraging to lose mojo when losing a battle.
Thanks for listening...
