Question on crafting

[MN_14]

Waste not II rotation is by far the most reliable way to do the current 2 star crafts if you aren't a specialist, but that's all I use it for.

Also, you can easily use the extra CP from Comfort Zone and Tricks to make careful synthesis II completely irrelevant, that's why I didn't rate it as highly.

Waste not II is definitely a useful skill, but it's also a double edged sword. There are many cases in which I forgo the use of WN2 in order to come up with a better rotation on the fly. Over-reliance on it can sometimes be detrimental.

CS2 is useful in that it's more powerful than basic synthesis, possibly allowing me to use tricks of the trade one extra time when using maker's mark/FS (depending on my craftsmanship stat of course). Since it's RNG free, it also can save me 22 CP in some cases.

I don't consider either to be essential but recommend having them both available if possible. When crafting base 2* materials, I usually have both equipped.
