And in the other direction, maybe we do need a difficulty below explorer's mode, as ludicrously easy that mode already is to most people, just so there's the most freedom. It doesn't seem like it would be too much work to implement an ultra-easy mode that further boosts player stats.
I didn't find it
that ludicrously easy, though I admit I'm not the most tactically-minded person. Both the current difficulty levels were bumped up with the last release though, and the devs acknowledge it was probably a little too much: the answer to satisfying everyone is really for the harder difficulty levels to make their début, whenever that happens.
