Just saw the new army image for MAF, and Bit isn't in it. Do we know if this is a typo or if it's intentional?
Don't sell/trade your models just yet; I think it's best to wait and see what the book and army 6 say in a month.
If I was to speculate I'd say it was because she was introduced with the ITS 9 document, rather than a bigger update, so she was overlooked when the Profiles PDF was subsequently updated.
They don't update the PDFs. Bit's profile entry probably has a notation to say "available in X, Y, and Z sectorials"
Lets also not forget that the ACA sectorial list in their video was wildly inaccurate too and the ava of a lot of stuff was wrong.
