NDA LIFTED

So, the Cataclysm nondisclosure agreement is lifted as of today. The mmo-champion database is now filling with beta data and tooltips are filtering out of betaland. Here's a few things to look at.

First off, what kind of gear are we looking at? Well, the entry level 85 blues being found are itemlevel 352. Here's an example of one such item, FIreweave Robe. It has 320 intellect, 480 stamina, 219 crit rating, and 219 haste. We don't know what kind of spellpower 320 intellect converts to, but even at just 1:1 (which feels reasonable for the itemlevel), that's cracking 320 spellpower.

Demon Soul
A bit different than first expected, you don't fuse physically with your demon. (Lore: Only your souls fuse). It's learned at level 85, and it's a 2 minute cooldown. Effects:
Imp: +60% crit with destruction spells for up to 30 seconds, reduced by 20% every crit for 3 charges.
Voidwalker: All threat generated by you goes to your pet for 15 seconds (Amazing for soloing!)
Succubus: +10% shadow bolt damage for 20 seconds (no charges)
Felhunter: +20% shadow dot damage for 20 seconds (no charges - affliction mainstay most likely)
Felguard: +15% spell haste and +10% shadow and fire damage for 20 seconds (no charges - demo mainstay and not too shabby at that).

Soul Harvest (!)
9 second channel that regenerates 15% (not much) health and all three soul shards. 30 second cooldown. Cannot cast in combat, so this isn't evocate for shards.

Fel Flame
Despite the suggestion that it won't be a rotational ability, instant damage plus DOT refresh with no cooldown sounds pretty rotational to me.
