Pick between build1 and build3. I would recommend build 1 because build 1 is great at party play. Falconer3 build utility boosts party a lot(aiming, circling). SR3 build cannot boost party.
AoE is best on falconer3 build and sr3. On build 4, falcon1 is not needed. Circling is just useful for quarrel caltrops and musketeer covering fire and snipe. Build4 is lower on AoE than other listed builds.
Level speed best with QS3. QS3 levels very fast and easily after reaching qs3 running shot. Blessing with sacrament and cafrisun set defeats mobs easily during low levels. QS3 running shot does not have attributes so you cannot spend on that. Build 3 would level slowest before reaching SR.
Cost is higher on falconer3 build. Falconer3 builds need AoE attack ratio (for sonic strike and mergen skills). Need 1 character slot for falcon pet. Falconer3 attribute tosneet page, circling expand may be kept at lv1. Need hawk hunt passive to keep hawk from flying away. And need pre-emptive strike, sonic strike, and pheasant attributes.
SR build does not need AoE attack ratio gear. Use your cata’s pet to ride on. SR3 needs limacon: spread attribute, riding attribute, and gun passives. tosneet page
Build 1 use 2-handed bow, build 2 uses crossbow and pistol. Build 2 needs investment into 2 weapons. And you would have to unlock Bullet Marker. SR build only needs pistol once you reach SR. Drop bm1 if you don’t want to unlock it and pick rogue2 at rank 9 on SR3 build.
Builds with QS3 (running shot) and SR3 (limacon) do not have any down-time. Normal attacks are always available. SR3 can use limacon during retreat shot. SR build is very easy to play, just activate all buffs and start attacking. QS3 falconer3 procs sonic strike with pre-emptive strike during auto-attacks, and uses mergen skills during circling, and pheasant. QS3 pavise is a great mob taunt skill.
