Possibly returning to game with a VERY old RomPla JHDC build

Is this still viable? I can't remember if I had bugs or Scorps but IIRC the last time I worked on it it was still very Legacy, and was working on upgrading it with Delta stuff.

Is there a direct upgrade path that doesn't cost money and isn't going to require 2-4 hours of dailies every day for six months to finish?

Honestly I will probably just play through the story again, or just check out all of the new stuff. But every time I come back I get slapped hard in the face by a story boss somewhere so I want to make sure that my build won't have TOO much trouble in the story, and maybe an elite or two.
