You still get adds here but there's the option to have them less but you end up not getting the best items from re-rolls to make your game more bearable. I would think it matters more once the difficulty is raised but then that means you would have to face several more ads in the process if you're playing free.
The expansion packs opens up content like new subplots and classes but even those aren't enough to make me to bother further. The lasting impression is just playing for the eye candy and nothing else. Thanks for stopping by!
