Im back to point out how pointless you are.
Taunt - Reduces damage taken by players. Except the person who taunts. Learn the animations. If people are taunting you in a 1v1 they truly are terribad.
Guard. Yet again doesnt effect in a 1v1. And also guard is the most epic way of killing 2 people ever, with only a 5% dmg reduction.
You say you are given these Defensive cooldowns because you're melee. Van/PT are also a melee/ranged hybrid and have 2 defensive cds/ both are pretty pants and on longer cooldowns then yours.
And pretty much to do dmg on a vg/pt you have to be in there face 10m or less yes we have some ranged skills but our dmg is mainly from 10m or less.
I think your getting a bit offttooic, snipers dont have stealth.
