Gnomes: Mana potions are harder to leverage when you have a low mana pool. Yeah, I know that gnomes following JJ can get the best of both worlds, but you can't rely on finding a timely JJ altar.
The introduction of the crystal ball, the new apothecary preparation for schadenfreude spam, plus the extra gold that you get in multi-boss scenarios to fuel a shopping spree at said apothecaries, have all been massive
indirect buffs to the elves. Unless you have an item or class feature that triggers on potion consumption, elves are now strictly superior to gnomes, a total inversion of how it was only a few months ago.
