The default weapon crit damage multplier is 150% damage right? so backstab without any further effects is just 50% more damage for attacking from the back despite lower weapon base damage? Feels like it might need a buff if that's really the case, even if + crit multplier talents and items exist in the game.
That is correct, and I agree with your assessment.
Of note, the best crit damage multiplier increase is the 2-handed skill, which doesn't even affect scoundrels. It would make more sense as-is for the dual wield skill to give extra crit damage instead of chance.
Edit: I checked the thread. The post claimed that Vault (which always causes a Backstab) was positively affected by Rage. For me, it was the same damage with and without.
