The magic schools in D:OS 2 have a lot of skills which don't scale with INT and synergize well with physical classes.

My first avatar character in D:OS 2, which I beat the game with, was a Scoundrel/Aerothurge. It worked great. It was a "Position Master" rogue. Teleport and Netherswap were great tools for moving enemies around for better backstabbing. Uncanny Evasion and Evasive Aura were great. Tornado, Vaporize, and Pressure Spike can help manage surfaces.
