For this one, my argument would be stacking full STR still scales well for Split Arrow and having 100% damage against flying attribute is pretty much more than enough already for farming Roxona East.
There were 2 testimonials already and they said they are earning silvers really fast. But let’s say you do have better dps with having high DEX early on, that means you would still need a stat reset later on, not to mention, this increase in DPS wouldn’t really make farming tons more efficient on Roxona because the mob spawn timer can’t even keep up in the first place.
