Stat Priorities:
Gear stat priority will depend highly on situation, if FCing - your stat priority should be
Stamina>Haste>Int>Crit>Spirit. If you are healing either offense or defence, or even mid, your gear stat priority should look more like
Haste>Spirit>Stam>Int>Crit. Keep in mind that this is simply an opinion - and different people will use different things. This is how I like to gear.
