Warlocks:
Affli
- Fel concentration now also affects Unstable Affliction and Haunt
- Imp felhunter now only has two ranks (50/100% of the damage, +1/2% to fel intellegence)
- Death's embrace increased crit chance affects all shadow spells
- Eradication is 4/7/10% (not sure if it was changed, I think it was), only working with corruption
- Haunt is a 2s cast. Healing done still bugged though. Animation changed, now looks like crap (a white arcane missile).
Demonology
- Demonic embrace down to 2/4/6/8/10%
- Unholy power requires SL
- SL still is 15%
- DS sort of reverted: imp->+10% fire damage, wv->2%hp/4s, succubus->+10% shadow, felhunter->3%mana/4s, felguard->+10%fire&shadow damage and 2% mana/4s.
- MD changed: felhunter is now -2/4/6/8/10% magical damage taken (which throws my ability to tank Leo through the window. goddammit Blizzard).
- Demo emp: succubus isn't healed anymore, felhunter: all spells on it dispelled (gg ua). Requires MD.
- Love struck gone, replaced by Imp Demo Tac: requires demo tac, demon crit chance increased by 10(/20?/30?)% of your crit chance.
- Demonic empathy changed: +2/(4?/6?)% damage to the next three spells/attack when the other is critically hit. 15s duration.
- Metamorphosis now also reduces the duration of stuns/snare by 50% when used. the tooltip doesn't mention the pet anymore, but I haven't tested it.
- Mount summoning is in the new mount interface instead of the spell book.
- Inferno is a 15 min CD (not sure if it was changed before though), which means it might be useable in arenas?
Ruin
- Bane now also reduces the cast time of Haunt by 0.1/0.2/0.3/0.4/0.5s
- Molten Core increased to 5/10?/15? % chance.
- Aftermath is 5/10%
- Nether protection is now a 60% damage reduction (at 1/3 at least, but I guess at all ranks too) instead of immunity.
- Emberstorm is a flat -0.1/0.2/0.3/0.4/0.5s cast time reduction to immo instead of -2/4/6/8/10% cast time. Effect to fire damage unchanged.
- Imp Soul Leech down to 5/10%.
- imp conflag: when conflag is cast, reduces the cast time of next three destro spells by 10/??/??%. 15s duration.
- Eternal flames tooltip is in broken English. Seems now it's a 100% chance to do the old effect at all ranks, and now increases immo damage by 1/2/3/4/5%.
- Chaos bolt doesn't pierce through immunities anymore (can't be resisted, pierces through absorption).
I didn't check the base damage changes, takes too long
General
- Mounts are bugged. All old mounts are converted to scroll-like items, except they have no charge on them.
- the lights of IF are turned off
shame the DK riding skill learning is still bugged, you can buy it in Ebon Hold
, or just bugged
