Here is were you can give any quires of what armour you should upgrade/ what enchants to have on armour etc etc one of the players here will give some advice if you put down the states of the armour for example the level of the item (what you need to be to wear it) any extra states the item gives, then the upgrade to that armour that you have just got and cannto decide which is better.

And also any quiries you may have on how armour works e.g. hit rating, crit rating, dodge rating, defence rating, resilliancen etc etc i am sure one of us will be able to help answer your questions

i dont know of alot classes but i do know the hunter armor.
its best for the hunter to have:

Agility : crit chance
stamina : your health and of your pet
interlect : mana

attack power : ranged attack power (no strength)
critical strike rating : crit chance
hit rating : hit chance
haste rating :speed

that is basecly the thing you need as hunter
