Why Ingenuity I and not Ingenuity II ?

If you have the 347 in craftmanship needed to make the 2 star craft items hard on your gear you can finish any craft currently in the game with ingenuity 1 and 3 x carefull 2 making ingenuity 2 quite redundant.

Ingenuity 2 isn't really a skill you eventually need/want as it is now, it just one that may help when you try get your skills/gear together.

Byreot's Blessing on the other hand is almost essential for 2 star 100% HQ crafting, especially if you have to work with lots of non HQ mats.

That said when new recpies come things may obviously change.

This is definitely not the case for my rotation. Without Ing II I would need 10 more craftsmanship due to the face that IngII will only cover 2 of my CS2s. Below is the rotation I use.

IQ > CZ > WN > SH2 > BT x5 > SH > GS > Ing II > AT > GS > BB > CS2 x3.
