15 aura rolls i wouldnt keep personally. people look at aura first and perf ed on a lower dmg item like bow doesnt hurt as much as aura. also zons have crit already so a lower crit roll doesnt hurt as much with diminishing returns on pts.
med level doesnt matter as much on a bowazon since ull always regen even with the lowest roll spamming guideds, dmg+crit>
even if u want to argue chucking furys, u shouldnt if u dont run some +mana on gear to not run out after a few throws
my 2 cents
