what is best base for a bow

grand matron or matriarchal

how many attack speed i need to get the max fast with each other??

best is subjective based on rest of gear/who/what u dueling

gmb is highest max dmg, needs 95ias with 14-15 fanatacism

matriarchal needs 45ias , unsure if fanata needs to be 14 there too

That depends on the gear and if it is PVP or PVM. Give us more details and we will be able to help you out

Max frames with shadow/diamond bow with 14-15 fanat is 65ias

Good balance between matriarchal and gmb
