Return of Reckoning

Hello, I would like to know if in warhammer there is a class similar to wow's dk.
I was thinking about chosen or marauder for different reasons, but I'd like to know from someone who has played more than me (leveled both at around 10).
I know about the different roles tank/mdps, I'd just like some informations about the classes endgame gameplay

Thanks

DK you do dmg and heal , try dok
