We have so far discussed the basic backgrounds of hunters and their talent trees and have mentioned stats on a number of occasions. Stats is a term given to the character attributes. If you open your character panel (C) and click the arrow on the bottom right to see your stat side panel, you'll see what basically makes your character tick. These numeric values is what we are talking about when we talk about stats. The ones that interest us from a hunter's perspective are base stats and ranged stats.
Base stats are the primary stats of all characters. These define our health pool (stamina), mana regeneration (Spirit), and basic damage/healing output (Agility, strength, intellect depending on the class). All base stats except Spirit cannot be reforged. The only primary stat of interest for a hunter is Agility. Agility not only influences our Attack power, but also our critical strike rating.
1 Agility = 2 Attack Power + 0.552 critical strike rating (0.0031%)
It is by far the most useful stat for us, and we should strive to attain as much of it as possible.
If you scroll down to our ranged stats, you will be greeted by what we term our secondary stats. These would be Hit Rating, Critical Strike rating, Haste and Mastery. These stats also directly influence our DPS output, but not to the degree that Agility does. Secondary stats all have different effects on hunters and their effectiveness can differ from spec to spec.
The importance of Critical Strike Rating, Haste and mastery differ depending on the hunter spec chosen.
FunFact: Why don't Warriors enchant their weapons with Intellect? Well, because they don't want their weapons to be smarter than they are, of course....
