Well the payoff was always pretty brutal, but now that you have to juggle both health and mana it doesn't reduce advanced use to focus mana -> cake. I was secretly hoping something like this would happen, it was a good thing it was de-spotlighted for a long while and lots of fun stuff happened as the perception of the power curve peaks was adjusted and the meaning of the word optimal as well - but it's nice that cydstep it has "advanced shennanigans" again.
How worthwhile it is is not really relevant - someone will find a way to weaponize it soon enough
But healing potions love is a nice thing
Also gives naga cauldron a whole new meaning. Shame you have to scumm for it if you want to focus it.
