Once you're outside its abysmal earlygame DaD

Cleric
By far the most boring class in the game thanks to a lack of options and passive playstyle Dark And Darker Gold. The amount of effort you have to put in between spellcasting jank and low mobility/survivability outweighs almost anything interesting the class has to offer.

Have fun being the least rewarding healbot imaginable.

Fighter
Easily the worst overall class in the game. Hotdog water perks and skills, no scaling mechanism outside of AC and some weight reduction, hilariously shitty starting stats, and the most expensive gearing in the game on top of it all.

Have fun blowing 2000gp so you can be as tough as a naked Barbarian with half the damage.

Ranger
The game is just too easy as Ranger, and running even the most basic bow build overshadows your other options to such a huge degree that anything else is blatant self-sabotage. My Solo Ranger had the HR extracts and GP of the rest of my roster combined, it's that good.

Have fun walking out of empty HR Infernos with 0 kills and a full backpack if you play remotely optimally.

Rogue
Once you're outside its abysmal earlygame with its dogshit PvE, this class makes Barbarian look like a varied, high-complexity class. The class that is actually designed around damage stacking and alpha striking feels like a joke in a meta that's already devolved into rocket tag, and everyone is better at it than you.

Have fun clearing every lobby until you suddenly aren't.

Wizard
Where do I even start? Easily the worst leveling experience and lowgear gameplay, while any remotely geared Wizard that possesses basic game knowledge becomes the world's best teamfighter and pubstomper, which essentially forces you to come up with ways to challenge yourself cheap Dark And Darker Gold. By far the worst gearing experience in the game, both for budget gear and high-end gear.
