If you really want to feel insulted, try playing a dual wielding frenzy barbarian. You either get your main hand attack and your off hand attack or you get your main hand attack and your frenzy attack. You don't get to attack with both hands and THEN add your bonus frenzy attack. Lol. It is the whole bonus action thing you mention. Just a heads up to anyone thinking of trying a dual wielding frenzy barbarian. Lol. Don't bother.
