Different fighting styles

[Arborinus]

I feel like this would just lead to people powergaming and just wearing gear under their armor for the bonuses without having fun with it.

From the title I thought of this idea: Players can choose one of 3 fighting styles in character preferences. Each style makes you stronger or weaker against the other two in hand to hand combat rock-paper-scissors style. You can't tell what other styles people have leading to some fun interactions.
