What do you use for your UI?

It’s best to use whatever tools you can get your hands on.  For example you should always use a spreadsheet such as Aldrianas which can be found at the Rogue section of Elitist Jerks.  But if you prefer in game advice try out the mod Pawn.

The thing to remember with Pawn is that it can’t work out set bonuses or trinket procs – for this information check out Elitist Jerks Pocket Guide to 3.3.

But I have some import goodness for you below for both Combat and Mutilate based off of Aldriana’s spreadsheet (I admit I haven’t added speed yet but maybe I’ll update soon):

( Pawn: v1: "Combat": CritRating=1.74, Agility=1.96, HasteRating=1.81, OffHandDps=2.45, MetaSocketEffect=5.22, ArmorPenetration=2.02, MainHandDps=5.82, Strength=1.1, HitRating=1.86, ExpertiseRating=2.15, Ap=1, GemQualityLevel=81 )

( Pawn: v1: "Mutilate": CritRating=1.72, Agility=1.94, HasteRating=1.9, OffHandDps=2.46, MetaSocketEffect=5.22, ArmorPenetration=1.19, Strength=1.1, MainHandDps=3.28, HitRating=1.84, ExpertiseRating=2.31, Ap=1, GemQualityLevel=81 )

This should help you in-game loads and will basically show you a tooltip like this:
