So the Crucible has released.. Thing is I never did Act 7 exploration only completion so I have barely any experience fighting the previous bosses and only did the 7 star carina challenge and 7 completion just to go to act 8. Yes I am valiant but never bothered doing the exploration of act 7. So, with the paths and rewards structure for normal and legendary difficulty revealed... should I do normal difficulty just to get the idea of how the bosses work or directly go to legendary difficulty?
