Certain warrior souls, such as Paragon, offers a 21 pt skill "Bend like a Reed" - which increases parry by +75% for up to 10 secs. That said, you generally start around 5-6% parry by just having some +parry on your gear. With Duality of Mind, you are picking up another 5% parry from generating AP's.
My experience vrs melee heavy fights, has been that I can rotate "Bend like a Reed" every 20 seconds from the time I first use it, as it only has a 30 sec timer, and last 10 secs. So now your getting 10 sec of melee immunity every 20 secs.
Now, couple this with the rest of my build that I listed (Paragon - Pally - Warlord) and decent gear, your block %chance is upward around 55-56% and your mitigating around 50-60% of those hits. Add this in with 2 disarm skills from the build, and you can effectively mitigate a large chunk of damage vrs heavy hitting trash pulls.
Deepstrike Mines for example, has some nasty hard hitting trash pulls that will leave your healers crying if you screw them up. If your using my listed build, you will generate AP's very fast, and can start rotating your parry mitigation after 2 hits, thus giving your healers some wiggle room while dps burns at least 1 target.
A rotation I will commonly use is:
Lights Decree > Shield Charge > Aggressive Block (macro) > Bend like a Reed > Sweeping Strike > Pacifying Strike > Pacifying Strike > (macro) > Lights Decree > Pacifying Strike. At this point, I work in Predictable Movements for another 3 fully mitigated reflected melee hits, then add in reactive Disarming Counterblow, then another Bend like a Reed soon after, with a back up Weapon Blow (another 5 sec disarm).
For those who want a heavy physical mitigation build, check my link on how to set it up in my updated Warrior build post. Why I take this over a 44 pt Pally build, is because 1. Impassible Guard only adds dmg absorption and is on 60 sec timer, while the Paragon 21 pt Bend like a Reed is 100% physical mitigation for the same 10 sec, and only has a 30 sec timer.
Feel free to shoot me a PM or chat in vent sometime with any questions =)
