World of Warcraft: Wrath of the Lich King

A quick scan of the Death Knight's talent trees gave a glimpse of the class' future: summonable runic weapons that repeat your attacks, unleashing blood worms, lots of spell deflection and minor self-healing, frost-based crowd control, turning yourself into a controllable Ghoul for 45 seconds when you die, exploding enemy corpses and swarms of unholy insects. We already know that later skills include the ability to summon Ghoul minions and even resurrect players as Ghouls they can control, with Ghoul abilties.

Starting at level 55, however, the mechanics were simple and the pace a touch slow, but it's obvious these concerns will melt away in the space of a handful of levels - the rune system pretty much guarantees depth. But depth isn't the problem. What the Death Knight needs to achieve to revive the art of tanking in WOW is a gratifying sense of power coupled with easy-access utility, and it's immediately, patently a success, thanks to Death Grip if nothing else. We've no doubt that WOW's first new class in four years will be another classic from the masters of class design.

Talent show

It's hard to know which of the challenges that face Blizzard is harder; introducing a new class to such a stable and strong line-up, or developing the existing ones without either imbalancing or them or undermining their personalities. On the latter, it's harder to tell if Lich King will be a success, with only talents to go on at the moment.

It's certainly true that some talents shout a lot louder than others. Fury Warriors get Titan's Grip - the ability to hold a two-handed weapon in one hand, although it slows your attacks - and it's not even their top talent, that being a Heroic Leap that slams, damages and stuns enemies in a small area where the warrior lands, sounding almost like the Barbarian skills shown in Diablo III on the same weekend. Protection Warriors are also well looked after, with free Shield Slams and a Shockwave that damages, stuns and aggros enemies in a cone in front of them.

None shouts louder than the Demonologist Warlock's Metamorphosis, known within Blizzard as "Illidan Form" because it transforms the player into a demon for 45 seconds that shares the same - absolutely beautiful - character model as the Burning Crusade raid boss. You get full health and mana, 360 per cent armour and a limited line-up of demon abilities: a charge, a shadow bolt, fire area-of-effect damage around you, multiple-enemy melee attacks and a fear spell.

Other show-stoppers are Enhancement Shaman's ability to summon spirit wolves, Shadow Priests' ability to disperse into pure shadow to massively reduce damage taken, Holy Priests' Guardian Spirit that follows party members and dies in their stead, Fire Mages' transformation into living bombs, and Balance Druids' Starfall, a rain of up to 20 stars that do both direct and area-of-effect damage.

Less showy but more intriguing top-tier talents include Subtlety Rogues' Shadow Dance, which instantly pops them into stealth every 3 seconds for 9 seconds, and will probably cause howls of rage for every other class in PVP; and Restoration Shaman's Spirit Link, which distributes damage between a friendly target and its nearby allies, a very interesting threat-management skill.

In terms of the more profound changes discussed at the panel, the Hunter seems to be getting the biggest overhaul in Lich King, with the new pet-training system. This dispenses with pet skill points and replaces them with a trio of talent trees for Hunter pets, one that enhances tanking, one that increases damage, and one that improves all-round utility. Could pet tanking in a group become truly viable as a result?

Also interesting were that Shaman totems would be streamlined, affecting the entire raid rather than just the party, and the class would also be given an emergency crowd-control spell called Hex. Meanwhile, Rogues will be allowed to sap beasts, dragonkin and demons as well as humanoids, giving them a lot more utility in dungeons.
