Well, at least the homework becomes much easier when you find the World of Warcraft Gem Finder. If I want to know which give +spell dmg, it's just a click away. Spell damage in a blue socket? Two clicks.
Very nice. Not quite PayPal donation nice, but nice.
Btw -- thanks for the comment earlier. Will post soon about the +nature damage, which I do tend to use over generic +spell for PvE leveling. After a quick review of the Nordrassil Raiment, I think the much less expensive +nature dmg gives Tier 5 armor a run for its money. Pre-70, obviously enough, I think "of Nature's Wrath" is tough to beat.
Now I haven't run any mathes against "of Arcane Wrath" and starfire, but when you can grab that +617 bonus every two seconds, 1.5 if you crit, well, I think it's the pure speed of wrath that's most important for maxing out your gear's bonuses. I do start with starfire, as things haven't changed much since level 62 or so.
Starfire to pull
Moonfire for DoT
Vengeance of the Illidari or the like
(reupping roots and moonfire as necessary)
The only thing that's changed for panzering is that I'm using the Braxxis staff now instead of Ursol's.
Panzerkin with Braxxis
Starfire to pull (occasionally if starfire stuns, I'll use Vengeance of the Illidari)
Wraths until mob is on me (Nature's Grace pays off here)
Moonfire (followed by Wrath on criticals)
Wail with Braxxis
(re-up moonfire every ten seconds, and follow with Wrath if Nature's Grace procs)
