Larian Studios Forums Divinity: Original Sin 2 Divinity - Original Sin 2 - Help/Tips/Tricks Rogue or Shadowblade for Scoundrel+Poly?

i want to play a "rogue" type of class, so i was going to make a rogue but i saw that Shadowblade already starts with the Scoundrel+Poly preset, so i came here to ask this question. whats the main differences between Rogues and Shadow blades and wich one is better for this combination?
