Question about dungeon drops and gear in general.

[Anova]

You can only get green and pink dungeon drops from dungeons. Unfortunately, it is completely up to luck of the draw with dungeon drops. Sometimes you'll get the full set, other times you'll have to keep grinding.

Dungeon uniques (green gear) is the equivalent to a hq item 4 levels higher than the level it is designed for. That means, you should probably start looking in to hq upgrades starting at lv.20 to replace your Sastasha/Tamtara/Copperbell set. Alternatively, Hatalati has some decent lv.20 green armor drops, although it is a bit uglier.

You will generally level with a combination of green and pink gear if you run dungeons for your gear. The dungeon green drops will generally be the best of that level available to you. Crafted items can be as good as pink gear, with the added bonus of having customizable stats (thanks to materia). Keep in mind though that crafting hq items and melding them with 5 materia will be prohibitively expensive for you before your first 50.

If you grind dungeons and try to complete every set before moving on, you'll definitely be over-geared for the next dungeon. And if you have HQ crafts with overmelds, you'll be equally overgeared too. Most players aren't expected to have more than 3 or 4 items of the dungeon's level equipped when they first complete them.

In the long run though, dungeon drops will be your mainstay as crafting simply can't compete with blue and purple equipment. There are some exceptions of course, especially for those building specific secondary stats, but it's not necessary to go in to optimized builds until lv.45 at least.
