I am by no means rich, but have about 15M spare cash, I'm 75 range and training slayer (Currently lv60) should I keep going with DCB and broad bolts until 65 switch to amythest? or switch to BP and take the hit on cost? is it worth?

I haven't noticed much of a different with the bp after the nerf, so i would go with that.

Bp is only good on low defence enemies since the nerf, so if youre fighting something with high defence switch to dcb

honestly, msb i and rune arrows are solid for slayer.
