copypasting my post from the wotlk thread:
DISCLAIMER: LIVE TYPING FROM FEED
Chilton talking about DKs? Anyway, the sound's back now. DK's will use warrior gear, runes were decided as the resource system early on.
hunter:
No steady shot clipping? What does that mean? - oh autoshot will fire through steady shot casting
Different pet families... pet TALENTS? talents will overwrite the pet skill system
new pets for hunters, we'll see in beta
priest:
can cast a buff to friendlies which sleeps enemies striking them
spriest talent that gets a -90% damage buff, pacified but regens 6% hp/mana every second for 10 seconds
guardian spirit: travels around healing party members, if party member would die, the guardian spirit dies instead
(apparently all three are talents)
mage:
frostfire, not as good as frostbolt or fireball, but with an elemental build it'll beat both
mage armor: shortens durations of magical effects on you
druid:
roots usable indoors
flourish or nourish, short cast time heal, 1,5s depends on how many hots you have on your target
shaman:
totem upgrades, suffering from totem spam -> SoE and GoA combined! totems in physical school
raidwide totems too
earthliving weapon->healing bonus (replaces rockbiter), flametongue->+spell dmg, windfury stays, the frostw/e weapon gets boosted
hex: limited CC, turns enemy into a frog, can move but can't attack, pve behaves like poly, duration 8-10 seconds
rogue:
fan of knives, aoe damage, situational, rogues not aoe class
sap gets expanded to other mob types, beast, giant, dragon, anything with a skull and a brain inside (personal note: what about UD :p)
paladin:
ret paladins are difficult to itemize since they are unique in their item needs, will move to DK like itemization
"waaah, ret pala stole my sword, now they'll steal your armour too"
hand of purity, some reactive healing (oneshot Earthshield)
BoP and BoF won't overwrite other blessings anymore, might be renamed to reflect this
warrior:
shockwave and Bladestorm to make warriors feel more like warcraft 3 and feel that warriors are strong
shockwave upgrades prot warrior's damage and gives them more aoe threat compared to thunderclap
titan's grip for fury, was fake last expansion but blizz took it and made it real in wotlk
warlock:
demonic circle, teleport back, around 50 yrds, faster summon inside it
51pt demonology talent - demon form, shadowbolt is aoe in demon form, no pets
Q&A

at the hunter question confusion, talents overwrite pet skill points
WF TOTEM WILL BE A BUFF, ROGUES CAN USE POISON IN MH & FERALS GET IT
they'll try to work out warrior talents out from pigeon holing you to take certain talents to dps - working to make bladestorm and titan's grip are attractive to take and viable
Cyclone will not be changed
