Something I noticed and wanted to share

[Gorny]

Some skills have the ability to use more than one weapon type, for example with Barbarians and Whirlwind you can use either dual-wield, bludgeoning or 2H sword slot. By default, it's set to auto select. The way to change it isn't obvious, what you need to do in order to change the weapon used when Whirlwinding is to press "A", then mouse over the Whirlwind icon and press or click your middle mouse button to change the assigned weapon associated with that skill.

This may work with other skills or other classes as well.
