Need a little help guys

I want to play a reave build using onehanded and shield with the champion ascenancy.

Here is the skilltree i came up with :

It should be an armor and evasion character. My questions: Are there enough crit. nodes?,
what auras should i use? Does the skilltree look ok?

I's appreciate some advice.

you don't have nearly enough life in the tree, I would never plan a build with less than 150% life even in softcore.
trying to do a crit reave duelist is just way too many points to be efficient, you simply don't have access to enough crit in the tree, and trying to invest points in both armor and evasion as well as crit is not feasible.
I would recommend either looking for a non-crit champion build, or going assassin crit reave and investing in pure evasion.

I added some more life nodes. I will propably use arctic armor and hatred. With the 90% increased evasion and armor from ascendancy, the permanent fortify and the decreased damage from taunted enemies this should be a fairly tanky build. Layering shield, armor, evasion, auras and passives i would think i am pretty good.
