Choppa Build/Theory and Bleed Mechanics

[Faraso]

So I've been playing a choppa for some time but I have been mostly role playing the class as a mindless berserker, going all about offense. Recently thanks to server being down and me having a super boring job, I decided to think about some build possibilities. So I came up with the idea on using bleeds to bring down my targets (especially tanky ones), while being able to put out some nice damage and some survivability.
Here's the build: http://goo.gl/NTncNI

But then a few questions popped up in my head... Like how exactly bleed mechanic works,how's the damage calculated and how is it being mitigated???
In general what do you think about this build, any ideas,suggestions,criticism and knowledge are deeply appreciated.

Do you plan to fight solo or in grp? Your build is pretty much the same as I was running when I have tried to solo - except I have specced for Wot Rulez and Wear Em Down.

Bleeds arent that great. Your Yer all bleedin' now is used when u are closing on your target (do not reapply it, focus on other abilities). Bleed Em Out is actually pretty great cuz it increase in dmg over dmg. Jagged Edge isnt really good at all. Maybe except these situations when u r going to 1v1 tanks and plan to use heavy parry build with Riposte abd Jagged Edge.

In grp avoid hitting tanks if there is any other archetype still alive around ya. In solo avoid tanks too - tanks are mdps bane and usually they are able to outlast you or survive that long that there is a high chance to get spotted and raped by other orderling or ripper appart by wandering zerg even.
