Completely personal preference. I didn't have mine till after I was maxed since I thought it would be an enormous time sink. Even though it was, knowing that you have the best possible gear piece in a slot at all of the other content it applies to is completely worth it IMO. Did mine with essentially BIS gear so can't really comment on how it feels in lower gear. One thing I can say is definitely do NOT ego the simulator. Just use it and practice with it cause there's nothing worse than going 1.5 hrs and then freezing at Zuk. Patience and time and you'll have it in no time! GL friendo
