Stats and class scaling in TBC; what's really BiS ?

Hi people, (timestamps below) this video took a long time to make. I hope it's decent atleast, and maybe educative as well. It's mainly the primary stats that differs between classes, sometimes a lot. Hopefully this video helps you decide which pieces are good for which class. cloudy days:   / discord   1:39 Agility 2:40 Strength 3:03 Stam 3:27 Intellect 4:53 Spirit 7:12 attack power 7:51 crit rating 8:08 Hit rating 8:20 Spell Hitchance 9:16 Expertise 9:36 Haste 9:49 Making sense of it all
