Best class in the new races

Here am going to talk about which class will benefit the most from the Racial Abilities of each of the new races that are going to be introduced to gameplay when Cataclysm becomes online.

(Alliance) - Worgen :

• Two Forms (Racial) Instant. Turn into your currently inactive form. 1.5 sec cooldown.
• Viciousness (Racial passive) Increases all damage done by 1%.
• Aberration (Racial passive) Reduces the duration of all Curses and Diseases used against you by 15%.
• Flayer (Racial passive) Skinning skill increased by 15 and allows you to skin faster.
• Darkfight (racial) instant. 3 min cooldown. Activates your true form, increasing movement speed by 70% for 10 sec.

-The Worgen's Two Forms Ability is mostly a thing just for fun , no benifit are gained when using this ability.
-Viciousness is a good DPS increasing ability , though by not a big amount ... its a racial ability so nothing more is expected as it gives 1% more damage.
-Aberration seems to be in someway a good ability to reduce the effect of Curses and Diseases , yet its mostly the best when PVPing , like when fighting against a warlock or a priest .
-Darkfight , well for me that is one cool racial ... if you are a rouge , you get one more sprint , if you are a warrior you get one more charge ? ... and if you are a hunter , you get one more tool to get away when kiting ... so its really useful , specially when doing BGs at the levels 10-19 , or mostly running through the tunnel of WSG :P.
-Flayer is not that big deal .. you just makes you skin faster without a skinning knife , plus you get your skinning skill increased by 15 .

Summery:
- Worgen's abilites are directed to Non-caster classes , so most classes who will benefit are (Warriors , Rouges , Hunters , DKs) .





(Horde) - Goblins :

• Rocket Jump : Activates your rocket belt to jump forward. 2 minute cooldown, shared with Rocket Barrage.
• Rocket Barrage : Launches your belt rockets at an enemy, dealing X-Y fire damage. (24-30 at level 1; 1654-2020 at level 80). 2 min. cooldown.
• Time is Money : Cash in on a 1% increase to attack and casting speed.
• Best Deals Anywhere : Always receive the best discount regardless of faction standing.
• Pack Hobgoblin : Calls in your personal servant, allowing you bank access for 1 min. 30 minute cooldown.
• Better Living through Chemistry : Alchemy skill increased by 15 (and you gain bonuses for healing/mana potions you made; 25% more mana/hp from potions).

-Rocket Jump .. i thought they felt it unbalanced that Worgens get a sprint-like ability , while goblins don't have it , so they made one which gives the same effect -well nearly- , but in Goblins style .
-Rocket Barrage is simply the same effect as the Engineer's Hand Mounted Pyro Rocket , it is cool as one more ability of the global cool down when dpsing , and even when PVPing , and also its nice how they made it scale with the player's level , so it doesn't hit 2k when you are level 1 .
-Time is money , hmm ... haste is something which mostly effects casters , 1% haste is really good amount as it could lower some casting ability by 0.1 seconds , and it also effects your HOTS and DOTS incase of priest or warlock , to deal more heal / damage .
-Best deal anywhere , it really sounds great when getting items that are subject to faction reputation for the discount , so when you are going to get your mounts , its just the lowest price possible , and it could help you save 1k gold when you are going to buy the Epic flyer training.
-Pack Hobgoblin , is just some useful tool , nothing special .
-Better living through Chemistry , well this one is simliar to other racial , just like the one with Blood Elfs that increases enchanting , and one with Dranies that increases jewel crafting , so nothing special about it except it increases the potions effect on the player .

Summery
- Apperently Goblins are going to be lucky when picking caster classes , because of having one DPSing ability off the mana pool , more haste , and improved Alchemy as most of cloth wearers pick Alchemy as their profession. so i think the most classes will benfit the most (Priest , Warlock , Mage , Shaman )
