Based on Redcape's numbers which seem solid, here's a guide to pre-raid gearing. Each piece is best in slot considered in a vacuum (i.e. value of hit is 0 once capped, you'll have to figure that out) and I'm assuming you keep trinkets on cooldown. You should consider getting Trinket Menu, which automagically swaps click trinkets in/out when they are on CD. All items can be obtained without Honor or a specific profession; all gem slots are assumed to be
[Bold Scarlet Ruby], and if there is a profession specific item in slot that is superior that is noted.
