that seems like... a very extreme difficulty curve with those three options
like, pre-lg to lg is a difficulty curve, but going straight from nebulous 'lg difficulty' (esp. when lg has pre-grove behemoth and post-grove behemoth difficulties (then from that to temple 1, then to 'temple, but it has exploding voidlings')) but from that straight to Vexxar tier? I definitely feel like there'd need to be at least one more step inbetween 2 and 3?

It'll be interesting to see the ability to pick difficulty implemented though

Am also curious how the difficulty options would affect combat boards.

You can perform an investment to make it easier if youre purely after getting the board pet.

Via getting a lv 30 team of maxstat pets and gearing them apropriately. However the difficulty alterations seem like they could be used to cut those corners further?
