It's a spiritual sequel to Titan Quest. The whole promise of Titan Quest / Grim Dawn, is that you start with no class, then you choose one, and then a little bit later you choose a second one. You get access to the skills of both class, allowing you to build weird stuff. For example my last Grim Dawn run, I played a Oathkeeper Necromancer aka Opressor making it a Dark Paladin type who ressurect zombies and give them a ton of Auras.
New DLC is coming soon adding a Berserker class who has Druid type abilities like becoming a Werewolf.
