in the context of 5.5e 2024:
Two-Weapon Fighting + Dual Wielder or Two-Weapon Fighting + Hunter's Mark + Defensive Duelist?
The question is this because Dual Wielder combines perfectly with Two-Weapon Fighting (a third attack at level 4 as a bonus action), but the problem is that the ranger also needs the bonus action for Hunter's Mark. So the question is whether I should go for the feat that gives me a third attack or stick with the Hunter's Mark and take a defensive feat like Defensive Duelist instead.
In both cases, I'd be using two scimitars to take advantage of Nick's mastery.
