Alchemist: Experimental Elixir: Now scales with level, and 2 extra uses for free. The ability to now sacrifice a 1st level spell to create a potion is worthwhile, especially as you gain in levels. (9 & 15)Except most of the subclasses have almost zero changes. The only one with any significant upgrade is the Artillerist, and that's divided between "deciding this one subclass doesn't have to choose between its options" and "catering to True Strike optimization".
9th: You lose the temp hp but the increase to the abilities of your elixirs makes up for it.
15: The extra damage is great the changing of greater restoration and heal once per day to Tasha's cauldron is a down grade unless they add more potions.
