why would an ama every sacrifice 3 pm/170 life (from 30 frw on ladder, or 90 life on non ladder) for 15 ias to use a blade bow

it may work on a soso suure. but definately not an ama bow. thats where i said it was a fail

i would also like to see the Maths on that amp calculation, because i assume you did this with your bow vs mine rather than both our BASE stat bows, not counting the duped jewel?
very nice matri
does that spider have any base max/min??
