Quickest way to get full class set?

I just started playing again a few days ago after I stopped playing for a year or so.

Was wondering what would be the quickest way to get full class set right now?

I only have "Set Me Free" left to do for my season journey.

I'm playing as WD, lvl60 paragon, on SC.

And I also would like to add a few new friends to play with.

Thanks!!

Edited: Feels really dumb right now...just realize that they give you different pieces just for finishing some of the season journey....
