Yup i have regreted not having scout nor falcon.
Scout is better on newer content in terms of quest/ sneak clear
Where as falcon excel better in aoe clear.
A3/QS3/Muskeeter 2 is solo a Single target destoryer. Pretty much a world boss destroyer. Only a little behind fencers and dopple.
I am specing more on Dex right now. Cards setup depends on your play style. I am more of a casting musk then AA now since Casting musk down time is only 5seconds and it excel bursting way more than QS auto can do.
Like for e.g A 3 sec combo from BS + CF gives you up to 1million + damage .
With 15 second odwn time you can just AA meanwhile or rotate skills like snipe. butt stroke + snipe + Cf + headshot deals up to 4m cap damage in 10 sec with 5 second cool down on CF and 10 on hs -> running shot filling
That is uncomparable with DCG + RS gem. You are not losing any damage on down time as RS (auto attack) scale with butt stroke. So it depends greatly how you play.
As for cards you can go glass mole / ella it’s personal preference. I personally banking on GL since i am converting to high dex
