Title:
Best Solo Way To Farm Fg To Get Sets?what class to start with and hardcore or softcore??
Barbarian & Softcore.
Simply put, best feeder class to solo is Barbarian based on stats and items they can use. (my personal choice is different to the norm, so I go Guardian, but restricted to item selection and low stats.)
Softcore is a simple answer, that is because player base is higher, and the item exchange is higher in forum gold with Whites and other items.
Solo exploring is still hard if you don't have gear on either core, with Softcore, you will move more towards group runs because it is faster and you can gamble for the items dropped to be yours or another person(s).
If you want pure solo ... barbarian is the better class for those that want forum gold. Good luck with that though.
