Should I get Torna for XC2 NG+? After beating XC2 about half a year ago I recently got interested in doing a NG+ run and the Torna DLC.

Should I get the Torna DLC for a NG+ run (for the new blades and quests in stuff), or would it be better for me to do a full new playtrough with it?

Also: About how long in terms of hours is the Torna prequel story (Future Connected took me about 15 hours to 100% with some small exceptions) and should I play the prequel before or after the NG+?
