My point is Bounce Shot can’t chain-react, if you hit 6 mobs whitout Circling, you will still hit 6 monsters under Circling, the attribute gives you a 75% chance (at level 15) to bounce the damage to another target, but once, like every other ability.
Back in May right after Combat Update patch, everyone re-rolled Falc3 because it was bugged and it would make the attribute chain-reach to every ability thrown, indefinitely, you could clear a wave of monsters with just one Oblique Shot/Crossfire because the damage would keep bouncing off every monster, again and again.
Right now this doesn’t work, and its best use is with abilities influenced by AoE Attack Ratio, to allow you to hit more enemies in the first place and to bounce the damage or with special side effect to allow you to bounce off the side damage aswel (once).
@ihaveangerissues Crossfire explosion is affected by AoE Attack Ratio, under Circling you will hit more monsters and the explosion can trigger the bounce damage from Circling attribute aswell, same for Triple Arrow, that’s why these abilities are so strong under Circling.
The point is, it won’t chain-reach endlessly, it’s not meant to be, if you see any viceo where they do it’s probably dated May/June 2017 when we had the attribute bugged after the Combat Update.
TLDR It’s not a good combo, because you’re limiting your damage in the first place using an ability that won’t make any use of the AoE Def Ratio reduction of Circling, you’re only using the attribute which works with every other ability, you have better options if you’re not going to profit from the AoE Def Ration reduction, that’s why usually Falc3 go with Sapper3: Broom Trap hits more enemies than Bounce, bouncing off more damage aswell, so in the end you have done more in total (I’m not a fan of Sapper3 myself, but the combo is quite strong).
Feint+Barrage is strong indeed, but it’s more of the same stuff as Bounce Shot, you are not profiting of Circling itself but only of the Attribute, also, you’d have to go Archer1 to Pick up Rogue at Rank 5, this means a lower Multi Shot which is quite good as a Falconer3… at Rank9 this may be negligible since you can go Mergen 1 (which is quite OP with both Falc3 and Rogue1) but now there are better options imho.
