Why Ingenuity I and not Ingenuity II ?

[kukurumei]

Your reply is pretty much in agreement with my quote "very limited usefulness".

With 275 craftsmanship, the hardest progress craft you'll be trying is 1 star 80 Dura, using Ing I you would finish with CSII x 3, that would be ideal when ending with Ing - GS - BB - CSII - CSII - CSII.

So from my pov, it's hardly worth leveling a craft to 50 for a skill you'll hardly ever need, if at all.

There are many much more worthless skills then ingenuity II and much more worthless 50 skills then ingenuity II.

Even careful synth II itself is fairly worthless in the bigger scheme of things.

You're just trying to draw a line in the sand when there's really a net of arbitrary lines, I have tapped ingenuity II way before I tap reclaim/flawless/innovation/WN2, etc, etc, etc.

Heck I haven't ever tapped flawless/WN2/reclaim ever, and innovation for rare lazyness, so that already bumps ingenuity II to 3rd-4th place.
