Dual Wielding Made Easy - List & Flowchart

[Mikal]

More attacks means more chances to land sneak attack. If you miss with BB, you'll lose both that and the BB damage, if you miss with your first non-BB attack, you'll get another chance. Though rogues have other uses for their bonus action.

As you say, rogues have other uses for their bonus action. And that's why I said generate advantage. Rolling two attacks is the same mathematically as rolling twice for advantage (though of course you get more chances to hit with advantage on two attacks, yes).

Personally, I'd rather roll an advantage attack with BB than two separate attacks, which also leave my bonus action free.
Plus, it opens up War Magic OA Sneak Attacks to have BB.
