All of the other stances for Demon Hunter provide a small, yet without a doubt meaningful buff related to the style of gameplay that it's supposed to support.
Reaver gives you +5 SWA, Matador gives you +5 Armor and Desperado gives you +5 Hit.

+5 SWA is undeniably universal. It's just 5 more damage. +5 Armor is great. +5 Hit is also something you'd generally benefit from.

But the +5 dodge on Cobra Stance is something that easily loses all value. Most if not all evades are already hardcapping Evade buffs. Meaning that any competent dodgie wil lget no benefit whatsoever from it.

Simple suggestion;

Turn Cobra's +5 evade from a Bonus to a Base buff, similar to the Rogue main class skill.

This makes would easily elevate it from being "basically useless if you evade cap" (99/100 times you will) to "universally great for any dodge build", without being far too powerful.
