My main gripe with transmutation Wizards is that they are basically Alchemists, but not really... just like the Artificer subclass. Both have features that I would want in an Alchemist, but neither one does them particularly well. I wish they'd just the remove the Artificer Alchemist (does anyone actually like it?) and give the transmutation Wizard different abilities, then make a dedicated Alchemist class that really focuses on the main concepts associated with Alchemy, such as the creation and extension of life, and has an experimentation mechanic that goes beyond "haha I don't know what this simple potion is gonna do, despite having created the exact same thing 50 times already".
