I can understand difficulty has been ramped up in order to increase rewards, but this is just ridiculous. I'm currently oscillating between leages 6 and 5, got into a fight against a dude with 16k HP (highest I've ever faced so far) to evidently drop back to league 6. First fight in there got me an opponent at 1.9k HP, I'm back in league 5. Any way of having a middle ground or something? Like now against a 6.8k HP?
Also, if you don't have new events to go for, it would be worthwhile to at least put back older events every now and then in the meantime. It would make the game at least a bit more engaging and fun to come back to, instead of having literally nothing to do.
Just trying to give constructive criticism here, not trying to bash or anything.
