Witches can be so versatile in my head whenever I think of one. Maybe influenced by the type of capabilities they are intending to wield/unleash? Staves and grimoires, daggers and skulls, a shrunken head and bottle of elixir. Absolutely can see witches being a hybrid between ranged, support, and close combat melee. Very much a class with tricks and looming danger for other melee to close in on top of them. Their weapons should definitely be more unconventional and linked to a sinister purpose. When you look at a standard melee class with a sword, its pretty obvious what their intended purpose is. But a witch holding a book and a doll with its eyes carved out and mouth sewn shut, begs the question "what are they about to unleash?".
