It does still give you attack power or spell power depending on what your classes to help you out when you are trying to burst. That does it for the Horde moving on to the alliance and starting with the drain i this race gets to shatter resistance just like the undead as well as giving themselves and their party members and additional 1% chance to hit on all spells and attacks. You have to have the Norwegians often is now an instant cast spell as well as scaling with your spellpower adding in a nice healing overtime effect when your team is taking damage.
Moving on to the night elf this race actually gets buffed into wrath, they now have a 2% chance for melee and ranged attacks to miss on them as well as having a 2% chance to not be hit by nature spells. They also have elusiveness, which reduces the chance to be seen in stealth. And lastly, the biggest buff they did is to their shadow meld disability is now usable in combat and will actually break any cast on you as well as removing yourself from the enemies target and focus frame.
On top of that you can actually shadow meld incoming CSC is like blind or scattershot, you have to hit shadow meld at the exact same time that the enemy throws their CC at you and it will completely cancel their CC seeing as it is on the same level.
This is extremely powerful when used correctly seeing as it has many benefits and a ton of different scenarios and is definitely a game winning ability. Up next is the gnome now there it is virtually unchanged from WoW Cataclysm Classic. Seeing as they still have expansive mind they still have arcane resistance and they still have escape artists.
As you likely already know escape artists will remove any movement impairing effect off of you, which is extremely helpful for melees and a bunch of different scenarios making it a great racial. Moving on to the dwarf they are also very similar to their TVC form. They now have some expertise when using mazes get an extra 1% crit with guns and have a 2% chance not to be hit with raw spells.
They do also retain stone form which is an extremely strong ratio against rose decays Farrells and warriors since it not only increases your armor by 10%, but also removes any poison bleed and disease effect for eight seconds. Last but not least, we have the single most talked about race in WoW Cataclysm Classic, which is the human perception gets nerfed into the ground going into wrath, it is now a passive ability and to be honest, it doesn't really do much.
