These builds are not bad, but I disagree so much with the skill distribuition.
Multishot is not needed to be on the max, because you want to use Mergen skills instead, so these points can be put on Oblique shot that is very useful when you have a good weapon because it will be stronger than the Blessing - Sacrament auto attack and hit 2 monsters.
Taking out a point a two of Homing Arrow to put in Parthian Shaft and Arrow Sprinkle is a good option too, most of the time you don’t fully charge the skill anyway.
I would say about Sapper but I’m very biased about that so it will better if I write nothing about the skills of the class…
