D2 Vs. WoW heroes!

All high end D2 chars carry Enigma.
Have fun hitting people who have 0 sec cooldown teleportation.

It's hard to make comparisons without going into gameplay mechanics with D2. In-game, there is like zero story for any of the characters. The cut scenes aren't even about the heroes, they're all Marius explaining how he ****ed up progressively more.

The Wanderer vs Tyrael was awesome though.

You can always take everything in perspective, but it is very true that it is hard to debate something that has no actual cutscene material to it beyond revolving characters that are completely unrelated to the heroes.

I think the only ability we have actually seen in a cutscene is Blaze.

Diablo Characters win. Comparing as is with a gameplay perspective.

As some have already mentioned, the ability of high level diablo 2 characters to achieve 75% all resist, and a paladin achieving up to 95% elemental resist would severely handicap any attempts to one or 2 shot kill any diablo 2 character.

Items in diablo are stronger, and since someone mentioned that in wow you can improve items I will point out that in diablo items regularly spawn with sockets, this goes for magical and rare items too, so that you may have a very powerful item with 5 magical properties + 4 sockets which can be filled with 3 jewels or gems. It doesn't end there, A magical jewel can have 2 attributes but a rare jewel can have 3 attributes. 3 attributes on 4 gems on a rare item with 5 existing attributes makes for an item with 17 properties. Those propeties can be very powerful such as a 40% ED or 15% IAS.

Auras are very powerful and several characters have abilities which function just like the paladin auras, such as the barbarian shout which can raise all allies health by 100%+ for more than 3 minutes or the druid's spirit of thorns which can applies reflect damage to all allies(percentage of reflected damage to ranged physical damage).

The most important advantage that the diablo heroes would have however, is summons and hirelings(each with the numerous auras applied. Each character can buy a minion who can be equiped with weapons/armor. The act 2 hirelings each come with a different aura. There are six variants on their auras in total. Auras all work simultaneously.The necromancer can revive up to 20 monsters to fight on the heroes team. additionally he can summon a Golem skeletons and skeleton mages. A summoner necro can easily have around 40 additional men. The amazon's final skill on one tree is to summon a valkyrie warrior ally. The druid can summon 3-4 beasts.
The army numbers would be like diablo 50-80 against Wow +-10. Now factor in the buffing effect of about 10 auras (1 paladin, 1 barbarian shout, 1 druid sage, 6 hirelings + some top gear give auras) on each member of the diablo 2 team.

Just to give an example of what the wow guys are encountering. An army of 80 all with at least 75% resistance to all elemental damage and the players will have 75% all damage resist, all 80 will have life increased by about 300%, any physical damage done to any of them will be reflected at a ratio of 1 taken for 10 reflected(1000% reflection this on its own completely defeats every physical attack of the wow heroes because their strength works against them) All 80 will have their movement speed boosted by 50-150%, damage enhanced by 350%+ and all will undergo healing from the healing Prayer aura, before they even come within sight of the diablo team the wow characters will become affected by the holy freeze aura which will slow movement and attack speed to sludge. If the necro is not immediately polymorphed then he can also cast a curse which can reduce enemy damage within large AOE by half.

Having played both I am sure that the WOW heroes wouldn't stand any chance. Even the one and 2 shit killers would only be able to reduce health on a ranged character by about 10% per hit with all the buffs and percentile protections applied.
