Why Ingenuity I and not Ingenuity II ?

[kukurumei]

There is no need to finish a 2 star craft in 2 synth's, 3 is perfectly good. For a long time I was HQ'ing 2 stars while finishing in 5 synth's. Ing II has very limited usefulness and is not at all needed, Ing I is great.

On the other hand, Byregot's is a very important skill to have.

again, depends on craftmenship. There is a range where once you hit that craftmenship, everything magically becomes easier with ingenuity2.

A 370cp 100% suddenly turns into a 350cp 100% etc. or reverse.... a low craftsmanship becomes totally impossible to possible. (crafting with no AF is a pain without ingenuity2)

I've had to rely on ingenuity2 on serveral craft with a 275craftmenship because the job wasn't worth AF inventory
