Returning player - necramech

I haven't played in a couple of years. At the time when I remember quitting because I just hated farming for the necramech. I had completed all stories up to that point. After going back I see that to progress through any more stories I have to build this damn necromech. Is there any way around this? I'm thinking about just spending the platinum to unlock one. I'm hoping i'm missing something and there's a way around this. I remember finishing the Heart of Deimos quest but I honestly hated that location. So i'm dreading going back and farming tokens and crap to get this thing.
