Well falconer is an enemy debuffer. you subtract AoE def from them and enlarge the enemy’s hitbox. Falconer has a red icon, supposedly that means that it is a damage dealing class. Ignore said icon, falconer has no damage dealer DNA. It is a more support oriented class.
Schwarzer reiter and falconer both are from rank 6. So I’d take one or the other, not both. mainly because I don’t think there’s any skill from schwarzer that benefits from having enemies with less AoE def.
I’m an Archer 2 Hunter 3 Falconer 3. This path is lacking throughout in damage so I do not advice mostly because one must learn to work around the hunter’s pet.
I’d take Archer 2 Sapper 3 Falconer 3 just to try it out but I think it is also lacking in the damage department. Archer 2 Ranger 3 Falconer 3 seems to be decent but I do not know about rangers pitfals so I’d ask for someone else’s opinion on this one.
Scout for a falconer? if you go falconer 3 then you unlock a mini frost cloud ( a very good ground AoE, doesn’t hit flying type) but I do not think that scout 2 is worth it, that would mean you’re committing to scout 3 at rank 9 and that’s not ideal.
So to take a falconer route you need A2 as a base. 3 ranks of something and then 3 ranks of falconer. I don’t recall the classes capable of dealing AoE damage in the archer tree. but you need something that is dependant on AoE formula or limitless AoE to benefit from a Falconer 3.
You’re always welcome to try something else too.
