Evasion is far superior, I don't know why ESO haven't nerfed it into the ground to make it comparable with the Light and Heavy Armour active skills. Sure, you may get a shield defending you from damage, or being unstunnable but mofos we get a 15% + 7%(if you're smart and use 7 pieces of med armour) by my maths that puts us up around the 89% chance to dodge a weapon attack. Rolling is too hard and you never dodge anything. Evasion is where it's at.
Anyway, it's OP. Time for a nerf to Evasion or at least a buff to the other two so 80% of spell dmg is absorbed or, you cannot be stunned for a few minutes.
I'm sure it's coming when ZoS getting around to fixing the imbalances in the game, but as I'm feeling charitable I thought I'd let everyone know what they're missing out on.
