dont get me wrong i like the falchion volley build just fine i just like to try out stuff see what can work.
its not so much wanting to be out of ammo its more about the freedom to go ham and not be worried about running out of ammo .
necessary means is a 25% damage boost now (if it works) you take the 2 health on crit instead of prize bounty. and whatever you want in last 2 talents (health on kill and encore for me)
using the rapier your light attacks do over 1k on head shots, the off hand pistol uses blessed shots to deliver head shots over 5k which generates health from 2 sources and can be weaved in between each melee kill which as you charged attack on its shortest stab is doing over 2.3k is pretty much after every attack.
you can still tag gutter runners/ leeches to break their holds. with encore , 10% CD reduction and a high finesse melee weapon you can get the ult up every 40 seconds or so so its not like you have no ranged capacity.
And thats your fall back for when you run out of ammo so really who cares if you do!
so i run with a brace of pistols and just go ham
not saying its the best but it works well enough and its fun
