Warrior feels somewhat similar to blood dk, both use a big 2h weapon and can sustain themselves. Thematically they're very different though, warriors are kind of goofy but fun lorewise.

Closest to dh would be gun breaker imo but only because gb feels like you're playing a dps class even though you're a tank. Nothing in ff comes close to dh mobility and feel.

Summoner is probably closest thing to lock but only insofar as they both are caster classes with a pet, otherwise they're very different.
