I’m assuming you are referring to why I am switching?
If so, it is because that as I have been playing my archer over the months, I find myself using auto attacks, rush dog, and sonic strike more often than anything else. Strictly speaking, this is a playstyle choice that with the current Ktest allows me to do. A mobile archer that can deal damage while constantly being on the move or protected.
Now when it comes to the skills/ranks that have been rework and why I chose them before/after:
Take note that I have 4 Minotaur Cards and 4 Templeshooter Cards on. That means I have 4% chance to stun on physical damage hits and 4% chance to silence on missile attack hits.
Archer 1-2
- Nothing has changed much for me and my goals for these ranks. Sadly I do not have the room to keep it and fulfill my playstyle requirements. Multi Shot is at the amount of hits it would have been on if it were C2 anyway. Never wanted, needed or put any points into Heavy Shot, and Swift Step is meh to me. Kneeling Shot will be missed though, but like I said I want to be mobile.
Hunter 1-2
- With the nerf to durations (flat 5-5.5 seconds) on all of its attack skills, leveling up the skills only increase the damage of said skills. That is a very lackluster reason for me to keep 2 ranks. They don’t even work on bosses (As far as we know, besides Snatching) and all I got for Hunter rank 2 was a (now) worse version of coursing and an invisible catcher. With the build I have linked, I still keep what I liked about the rank and my playstyle.
Scout 1
- Nothing wrong with this rank. I will miss it and all the shenanigans I could do with it (Do a Barrel Roll!).
Falconer 3
- Nothing has changed, in fact it is better now than it was before. With this rank I can easily be the single derp dps I like to be and still excel when it comes to AoE when truly needed. These 3 ranks are staying!
Now as for what Quarrel Shooter can do for me that I want/lost:
- It has the defense abilities that I would have loss when not taking Archer 2 and Scout 1.
- Scatter Caltrops can be used as an AoE damage source and utility/CC.
- Running Shot will work with my playstyle at all times.
- Lastly Deploy Pavise helps with those times I would need to stay in one spot.
(This is only if current Ktest is to stay the way it is for said ranks)
If/when rank 9 comes out and I don’t like the choices I can choose from Scout, Archer 2, Hunter 2, Mergen, or whatever else that would benefit my playstyle or cover up my weaknesses.

@Sensate If I remember correctly, no. I believe it was patched out quite awhile ago.
