I'm raising a SP Tauren for shoots and giggles - its only 30 but I'm lovin' it!
I still see plenty of SPs in the BGs and they don't seem to have lost any of the effectiveness I remember them having back in Wrath, if anything, the bastards seem to be even deadlier then before.
That said though, my girl's got an 85 troll SP (url=http://us.battle.net/wow/en/character/kargath/sherina/simple]Sherina
[/url]) and even though she's pulling a 346 item level she's been suffering from both DPS output and mana issues - only pulling around 5k or so and goes OOM at the drop of a hat.
Any suggestions on rotations, gems, reforge, chants, etc?
For gear, the first thing I notice is the helm reforge. Really minor, but the hit -> spirit reforge isn't necessary. I assume that's for the Holy off spec, so yeah, that's perfectly ok.
There's two major things I'm seeing.
First and most importantly, below Intellect, Haste is our #1 stat. Everything needs to have haste on it. Everything
. It would be preferable if haste was on the item to begin with, but it needs to be there. I see a lot of gear with crit on it. Crit isn't bad, it's about equal to Mastery. But I really recommend reforging all that to Haste.
So, for reforging:
If it has haste, leave it alone.
If it doesn't, reforge Mastery or Crit to Haste.
If you have to choose between Mastery and Crit to reforge, choose Mastery.
Unless you're PvPing, +sta gems are fairly useless. Every gem needs to have +Int on it. Use Purified (Spirit/Int) for blue slots, and Reckless (Haste/Int) for yellow.
She's also about 1% above hit cap, so it's possible to reforge away some Hit to Haste. This takes priority over reforging away other stats. Being hit capped isn't even as important now a days, so you can dip below as far as you feel comfortable. I'm about 4% below hit cap, personally.
