"Newbie" question

[TechnoTechie]

Actually, as I said above, level 53 = 4 star. So L51 is actually below 4 star.

An important thing to note is that 1 level in Heavensward is effectively 10-15 levels in A Realm Reborn (or at least that's how big of a wall it feels like, especially when you're trying to do a level 51 craft at 50, but it's as hard or harder than a level 50 3-star craft); this makes every level above 50 that much more important to attain in reducing the difficulty of previous crafts.
