Since I got my Lei Shen trinket I went with about 9800 haste and saw about 5% up time. If I dropped down to about 6637 haste (aff offspec) with more mastery and crit would you think it would effect up time that much?
Also reading McDareth's post made me realize that I should Incinerate less and Chaos Bolt more. So I had few questions, I know you generally want to save your Chaos Bolt with Int procs. Lets say that you have 1 or 2 embers and you only have 1 Int proc (Lightweave/Jade Spirit/Eng Gloves) do you still Chaos Bolt? I think my problem is that I try to wait for at least 2 procs and that leaves me Incinerating more; then I end up getting close to ember cap and cast a Chaos Bolt with no procs.
