Sorcerer and Wizard are fine. They underperform a bit (not even by a huge amount) in melee and make up for it with tons of offensive and utility spellcasting.
FvS is fine because it has TONS of options and it's sitting in a fine spot right now.
I don't find Clerics fun to play, but Clerics only need a little melee love because they have SO MANY other options that they can use and have you ever seen a Cleric turned down for a raid? Ever?
Druids are sitting pretty right now and that's with Bears finally coming up to Wolf level.
Artificers are kind of lame and have ALWAYS been lame for melee, but they had about a year of being everyone's favorite splash, so I don't think they need a lot of love at the moment. They just had their turn.
Rangers should not have had Dance of Death nerfed. That was a Bad Thing(tm).
We'll see how Alchemist turns out. Time will tell if it's overpowered or merely "just fine".
Monk has some solid options, but they're a weird class. Their floor is terrible and their ceiling is pretty impressive.
And Rogue has never been in a bad place in the history of this game. They've never been on the top, but a decent player can have a really good time with a Rogue and it's one of the best splashes in the game.
And I honestly don't are about Bard even a little bit.
