So after having various discussions in other threads and getting different points of views, I have decided to leave it to the community (as another user did) to choose my class for me. I will attempt to solo the game (though it is not a no-reload challenge, it is just something I want to do in my free time for fun).
I have compiled a shortlist of classes that I have never really played much of before, OR classes that are traditionally considered a challenge to solo with.
Feel free to leave any additional comments if you like. Thanks for your help!
