Each class allows the player to create their own immersion. Identity is up to you and your imagination. I’ve reinvented my main many times over with just one class. Each time a unique experience.

You wear the same sets, use just about the same world skills, and use almost identical champion points for each of the 3 roles. The difference is some classes have better skills or passives that make them degrees better for certain roles.

I'm saying no solely cause of DK.

DK lost its identity and has slowly been regaining it. DK used to be a class about standing your ground and locking a place down. Now it is a shell of its former self. Inferno got turned into a projectile attack rather than a circular dot around yourself. Our wings were clipped. (Meanwhile sword and board gets to keep its reflecting skill, Warden gets a damage shield that prevents 3 projectiles from hurting you, and necros can use their bone armor to drag ranged enemies to them.) We still lack a proper stamina morph for flame whip. Every other class has a mag and stam spamable except for DK. DK has been killed by a thousand cuts, and the Deadlands update put a band-aid on them. I can only pray that the next update further mends their issues.

Not really, especially disappoiting when going for base game classes and picking the stamina route. You end up with 2 or 3 class skill if lucky, and the rest is a repetitive copy paste of any other stamina character with the same identical weapon/fighters guild skills.

I could literally be anything and it wouldn't matter.
