In traditional classic your race choice for
Druid was determined by your faction choice, as each faction only had 1 race that could be a
Druid. However in WoW: Forever, each faction now has two race choices for their
Druid. While the Skyrborne exists for both Horde and Alliance, they actually have slight changes in their racial abilities based on which faction they choose.
Horde
Tauren
With access to
War Stomp Tauren are able to control mobs and get out quick spell casts where the other races couldn't. It's also a fantastic pvp tool.
Tauren's other combat racial is the reworked
Endurance, which still gives the 5% extra health but now also gives 2% increased crit damage. This actually synergizes quite nicely with talents like
Sharpened Claws, making this a potent racial.
They also get access to a new Racial called
Plainsrunning, which allows them to gain an insane amount of movement speed as long as they keep moving. This, combined with their new cultivation passive that gives them random free Herbs in the world makes them an excellent profession grinder race.
Overall the Tauren are a very weird race to analyze with some of the most unique tools and abilities of any race in WoW: Forever.
Skyborne
The Skyborne on Horde and Alliance both gain
Walk on Air, which allows them to fall any distance without taking damage. They also get 3% haste, as well as 5% damage against elementals. On the Horde specific side, they gain a self cast buff that gives them extra run speed. This 3% haste is actually quite strong, particularly for
Bear Form rage generation from the increased attack speed. Its also decent for
Cat Form since a large percentage of our damage comes from auto attacks.
For PvP, Tauren is the stronger Horde race. However, for PvE, they are very close, with Skyborne slightly edging out Tauren. If playing
Bear Form in particular Skyborne really pull ahead.
Alliance
Night Elf
Elune's Light is insanely powerful for
Druid. It gives you 10% critical strike chance for 15 seconds, which has great synergies with both
Bear Form and
Cat Form.
Natural Instinct gives us 20% increased crit damage, and
Blood Frenzy gives us even more rage as well as bonus energy on crit. They still have
Shadowmeld, which is a decent passive.
Quickness still gives 1% dodge which is amazing for
Bear Form, and it now also gives 2% movement speed.
A lot of the power of Night Elf is based around
Elune's Light, which means fight duration plays a huge role in the power level of this class. For end game parsers, I wouldn't be surprised if Night Elf was the strongest. As for leveling, its still quite strong, and can be used in moments where you need a ton of damage.
Skyborne
The Skyborne on Horde and Alliance both gain
Walk on Air, which allows them to fall any distance without taking damage. They also get 3% haste, as well as 5% damage against elementals. On the Alliance specific side, they gain a self cast buff that gives them mana and health regen through Read Ley Line.
Now in general
Read Ley Line is going to be a fairly strong leveling skill, often replacing the need to drink with a quick Ley Line Channel. For Boomkins and Resto Druids, this is also a fairly strong combat skill as it gives you back some mana. However for Feral, this is not a strong combat skill.
On the Horde side I would suggest Sky Elf.
On the Alliance side and overall, Night Elf is probably the strongest overall
Druid race.
