The 0.4 league mechanic seems kinda mid

Has anyone found a way to make the new league mechanic worth doing?

I'm almost done with the campaign and my impressions are not very favobarle.

The poisitioning of rooms on the chess board seems largerly random which removes any fun of trying to figure out the best strategic path towards the boss.

Rerunning the same rooms over and over whenver opening the temple becomes boring.

It takes a lot of time and the rewards don't seem to worth it, at least early game.

How can you not enjoy 30 minutes of puzzle with 2 exalted orbs and 1 regal as a reward?! And these are not your typical regals and exalts... you cannot pick them up, you have to use at spot. Isn't that fantastic?
