I think they have came a real long way and creating a new class will require a good amount of time. I don't usually like DLCs, but I definitely am interested in D:OS 2 DLCs. Some new classes and maps maybe.
Please no. Paid DLC is why I stopped playing shooters 15 years ago. Well everyone just bought the $40 map pack. looks like I don't have anyone to play with. I hope you're referring to workshop stuff.
I think it is going to be easy enough to add a couple skills to get the class feel you're looking for after release of the editor.
