40k Eldar Strategy: In Defence of War Walkers

The Eldar Army list has the most varied, unique and (arguably) most powerful heavy support of any army save the Imperial Guard.

These are their choices.

Falcons (duh): The fastest, most reliable transport in the game, belonging to the army that has the best assault squads. And it has 3 big guns on it to boot.
Wraithlord: WS4 BS4 S10 T8 I4 W3 3+. Option to carry two Eldar heavy weapons. 'nuff said.
Fire Prism: Finally got their due in the new book. 115 point Predator, Eldar style (it flies). Provides S9 anti-tank, AP4 anti-infantry AND AP3/AP2 anti-MEQ.
D-Cannons/Support Weapons: They're freaking D-Cannons. Artillery rules keep them alive.

Following the big guns come Dark Reapers and War Walkers. Dark Reapers tend to get respect (cause they're kick ass) and War Walkers tend not to. There are reasons for this, the price ($$) per model being one of them. Much talk is had of guiding batteries of S6 shooting blah blah, I don't want to hear it. You shouldn't have to toss in a 100+ point HQ selection to make a unit viable.

I just want to mention: one mistake I had been making myself is that unlike the Wraithlord, if a War Walker carries two of the same weapon it does not count as twin-linked. It counts as having two weapons.

Imperial Guard Sentinels are the obvious comparison. They are both AV10 Walkers, they both get the Scouts rule and they are both BS3. Sentinels, unfortunately -- are a rip. Their only saving grace being the fact that they take up a Fast Attack selection in the Guard/LatD armies, with the bevy of strong Heavy Support choices available. War Walkers are no longer open topped, unlike Sentinels.

Sentinel w/ Armoured Crew Compartment and 1x Multilaser: 60 pts.
War Walker w/ 2x Scatter Laser: 60 pts.

'nuff said. War Walker: 1, Other Stuff: 0. Imperial Guard pay a premium for their Heavy Weapons, but the War Walker is still a great deal points wise. It even gets I4 and an extra attack. w00t.

Within the Eldar list, the closest comparisons are Dark Reapers, Vypers and Wraithlords. We can also include the Fire Prism, assuming it is shooting once. Hand-waving I'm going to consider the Fire Prism one shot at S9 to be equivalent.

Dark Reapers w/ Missile Launcher and Fast Shot (4 models): 182 pts. (2 shots @ BS5)
3x Vypers w/ Missile Launchers: 195 pts. (3 shots @ BS3)
Wraithlord w/ Missile Launcher and Bright Lance: 155 pts. (2 shots at BS4)
Fire Prism w/ Prism Cannon: 115 pts. (1 shot at BS4)
3x War Walkers w/ 2x Missile Launchers: 210 pts. (6 shots @ BS3)

Some simple math. Hits/point, normalized by x100:
Dark Reapers: 0.916
Vypers: 0.769
Wraithlord: 0.860
Fire Prism: 0.580 to 0.800 (hand-waving)
War Walkers: 1.429

War Walkers: 2, Other Stuff: 0.

Anti-infantry.
Dark Reapers (4 models): 140 pts. (8 S5 shots @ BS4)
2x Vypers w/ 2x Shuriken Cannons: 120 pts. (12 S6 shots @ BS3)
Fire Prism w/ Prism Cannon: 115 pts. (6 S5 shots at BS4) (pie plate == 6 models, hand-waving)
2x War Walkers w/ 2x Scatter Laser: 120 pts. (16 S6 shots @ BS3)

Math. Hits/point, normalized by x100. This counts S5 and S6 as equal:
Dark Reapers: 3.810 (AP3)
Vypers: 5.000 (AP5)
Fire Prism: 3.478 (AP4)
War Walkers: 6.667 (AP6)

Go War Walkers. Fire Prism does better if you can get more models under the template, and shines against 4+.

War Walkers: 3, Other Stuff: 0.

Anti-MEQ.
Dark Reapers (4 models): 140 pts. (8 S5 shots @ BS4)
2x Vypers w/ Star Cannon and Shuriken Cannon (counts as one additional shot): 160 pts. (6 S6 shots @ BS3)
Two Fire Prisms w/ Prism Cannon: 230 pts. (6 S6 shots at TL BS4) (pie plate == 6 models, hand-waving)
2x War Walkers w/ 2x Star Cannon: 160 pts. (8 S6 shots @ BS3)

Dark Reapers: 3.810 (S5)
Vypers: 1.875 (S6)
Fire Prism: 2.319 (S6)
War Walkers: 2.500 (S6)

Ouch. Reapers 4TW. Note that if you take into account cover saves you're better off or about the same with Scatter Lasers over Star Cannons, at least against 3+. Terminators are another story. Starcannons might be worth it against Terminators but I prefer to use our old friend the Shuriken Catapult. So as it stands call it

War Walkers: 3, Other Stuff: 1.

So War Walkers have their uses, and could be considered a valid use of a Heavy Support slot. Before I got carried away, all I really wanted to show was that the Eldar Missile Launcher is a great weapons choice. Cheaper than both the Starcannon and Bright Lance, it comes with a longer range of 48". Great for keeping the more fragile War Walkers and Vypers out of harm's way. So for 140 points you get 4 Missile Launcher shots at BS3 with 48" range. The War Walkers have Scouts and get 3d6 for their difficult terrain roll, allowing for a chance at key flanking deployment. While understandable, it's a shame they aren't a Fast Attack choice giving them a later deployment. Very important for a flanking unit. In addition, the blast on the EML is AP4, and even forces a pinning test. The Scatter Laser battery also makes a very viable choice, coming in at 120 or 180 points.

Personally, I'd probably just take Reapers and Fire Prisms. I have the models, for one. I think they're fun, for another. Dark Reapers really put the hurt on MEQ, and Fire Prisms have very unique versatility (at the cost of two Heavy Support selections). War Walkers are a good fit in a two Falcon Army, giving them some serious anti-armour fire support they could be missing.

And yes, you can even combine them with Guide. XD
