Eq for ranger

Better is armor ? or Evasion ? in chest or other parts equipment?
Please answer quickly :) Thanks alot.

Firstly I would like to mark, that I'm not using my own knowledge nor expernice, but something i read in this forum.

Generally evasion allows you to... evade enemy attacks from time to time, while armor reduces pain in a passive way. All in all - armor's better.

But! Ranger is very potential to get evasion nodes - i.e. can point nodes for 68% with pretty low cost in the nodes.
Secondly he may point Iron Reflexes - which is very near too - allowing to convert all evasion into armor.

This would mean, that it's better to:
1. having Iron Reflexes - wear evasion items
2. not-having Iron Reflexes - wear armor items

Now I can only ask someone who is wiser than mine humble person about:
- correctness
- does evasion nodes works before or after Iron Reflexes.
BaseEvasion*(100% + nodes bonus)=Armor
Or
BaseEvasion=Armor, following by BaseEvasion*(100% + nodes bonus)=0

ok thanks u :) I think i go to iron reflexes.
