Scoundrel has no baring on "hybrids"
It increases movement and crit multiplier
I am a bit hesitant in wanting to agree with you here due to the context; you're taking that component without considering the whole.
He's saying aero (int) + scoundrel (fin) which implies he's divving his attr points accordingly which means one of his weapons is going to be a dagger or even both or maybe single handed.
So that translates to some of the following possibilities; Shadowblade; Spell Crit/Ambush build.
Is it competitive relative to other options? Possibly maybe. You can, after all, dual wield wand + dagger so you get skills like Fatal Blow, various positioning things, and also backstab. I haven't tested this out, I am just going off of logic. So, backstabbing guerrilla wand damge + physical dagger damage while casting relatively decent hitting nukes with high crit chance using Scoundrel and Aero to catch up in damage efficiency and ... Chloroform ... deals magic damage and scales off of ... finesse? Maaaaybe?
