- Eldar have fewer vehicle options compared to the Space Marine and Ork.
Eldar: Viper (skimmer), Falcon (transport/anti-infantry), Fire Prism (artillery).
Space Marine: Land Speeder (skimmer), Whirlwind (artillery), Dreadnought (melee), Predator Annihilator/Destructor (anti-armour/infantry).
Ork: Trukk (transport), Deffkopta (skimmer), Killa Kan (anti-armour), Deff Dread (melee), Bi Trakk (tank/artillery).
- Eldar have 2 heavy infantry units which fill the anti-armour role, and might explain why there are so few vehicles in the Eldar rooster (though Orks also have one heavy infantry unit), but they also overshadow vehicles.
Because Wraith Constructs are infantry they beneficiate from infantry upgrades, which means you don’t have to spend requisition on new upgrades, and they’re relatively cheaper (energy-wise) than Falcon/Fire Prism, making them a more viable economic option. Moreover with the appropriate doctrines (Rift Blast + Enhanced Battle Focus) Wraith Guards can be both anti-infantry and anti-armour with a decent rate of fire, meaning that they’re more versatile than Eldar Vehicles. They also are more resistant while being less mobile, but the Soul Recall means you can save few of them during a bad engagement.
Viper is a decent skimmer, fast and dealing pure damage, however due to its low fire rate it feels really underwhelming, particularly compared to a Land Speeder with multi-melta gun. An increased fire rate would make them more viable, particularly in hit&run scenarios.
Falcon is great, at the moment it's the only reason I’ll construct a Sky Portal.
Fire Prism is a decent as artillery though it’s definitely underperforming for its price (100/375), particularly compared to the cheaper Whirlwind and Big Trakk. The Superheated passive is also too easy to read because the effect is super obvious. The Big Trakk has a similar delayed explosion when in artillery mode, but the effect is more subtitle and not screaming “move now!”.
