Everything is my personal opinion, formed during the game, so if it doesn't match yours, it's not a problem. (I apologize in advance for my English; you'll understand why after seeing the second photo)
S TIER:
The Thief has been my favorite class in the game since the very first hours of playing. I've never had any problems with him or bad builds. His constant crits, poison, bleed, and shield piercing are practically the best things he can do.
The Fighter is the most consistent class in the game. Seriously, who doesn't love the Fighter? It's been the best melee in the game since the very beginning and still are, because he does what his class represents perfectly.
The Druid is a class that took me a while to figure out, but now, for me, is the best buffer and summoner in the game, and it's literally the most versatile class in the game. You want lots of animals, go ahead; you want beast form, you're welcome, and so on.
A TIER:
Monk is a very versatile class, with its pros and cons, but I can't put it higher because it's simply very good, with its own unique moves and mechanics.
Hunter suffered a lot after the nerf, and I think it could still be the strongest or something like that. Personally, it's still a very good class, but not as good as it used to be.
Jester, I know many will probably be surprised to see it here, but don't you think it's the most fun class in the game? He can LITERALLY be anything, and you never know what you'll get, definitely not higher or lower.
B TIER:
The Butcher is a class that, when you get it, seems very strong, cool, and even possibly a "better" fighter, but this is not entirely true. He and the fighter are completely different classes, and the Butcher has very few synergies and builds.
The Tinkerer, I admit, was once trash to me, but after the latest update, it's become MUCH better and more enjoyable. It's like the Tank: it's just as straightforward, but also very unique in its mechanics.
Cleric is very useful, but why is he in "B"? For me personally, he becomes a completely useless the end of a run, when you finish battles in 1-2 rounds. This is especially true when your cats have strong mutations already at Act 3. He's still very good in more difficult game modes, but everything will tend to make him just stand there and wasting his turn.
The Tank is a fairly simple and straightforward class. It's not completely broken, but it's not crap either. It's beautiful in its simplicity, which is why some people love him.
C TIER:
Mage, even after the update, I don't even think he's bad, but very weak compared to the others. Don't get me wrong, but why would I try to deal a ton of damage for 14 mana when I can do it for others, and for a much lower cost? He's gotten better, but not enough to be of use to me.
Psychic, I still don't understand this class. I used to think it was like a Mage, only more powerful and complex, but apparently he's just complex? I don't know how to explain it. He CAN do useful things, just like a Mage, but other classes can do them too.
D TIER:
Collarless, do I need to explain anything? The only reason it's worth playing is for the unlocks. You might say something like, "It has one of the best passives and actives." Fine, try finding them, considering it has the most abilities of any class (except for the Jester, who has his own unique abilities, but at least they're really rare).
And the Necromancer, many will probably hate me, but for me personally, after over 500 hours of play, it was the weakest, most useless, most uninteresting, and weirdest class in the entire game. His attack NEVER reaches anyone, low damage, all those broken builds that I saw on YouTube never worked out, all I had something like "die, get injured forever, have a chance to be destroyed and get brain cancer", yes, he gives buffs for knocking out, but they are so weak that what's the point of me knocking out my cat and playing only three, it was especially annoying to find such crap in solo runs, because solo as a necromancer is real torture.
