Tanks and frontline melee are the primary users
+Dodge: This increases your chance to dodge a melee attack by a percentage. Tanks and frontline melee are the primary users of dodge though and you won't need wow gold to load up on it.
The exception is if you intend to be a Survival specced melee hunter. In that case some dodge might be useful, but it will be hard to find. You need 19 dodge rating for one extra percent at seventy.
+Parry: This works like Dodge except that it lets you parry an attack with your weapon. Just like Dodge it is only worthwhile for front line fighters, but it is less useful since it requires that you have your weapon drawn and some attacks can’t be deflected.
However, if you are going to be a Survival specced melee hunter this is more useful than Dodge because of Counterattack. You need 31 parry rating for one extra percent at level seventy.
+Melee Crit: Whenever you swing or shoot your weapon you have a chance of landing a critical strike. In addition to your crit chance from agility you can also get crit chance from armor as well.
In melee and ranged this is one of the best melee modifiers you can get and depending on your spec you will want to load up on as much of it as possible.
+Spell Crit: This works like Melee critical hits but with spells. Since hunters don't have any spells though it is useless.
