Winds of Death - Rasheth Gunline

Supposedly, but is it worth taking him with just one unite of reivers?

I'd say one major issue, and this is the main issue our theme has, is that there's nothing to receive a charge from the enemy. In WoD, your only options are Brutes, Sentries, and maybe Rhinodons(?). In your list, I'd switch out the bronzeback for a pair of Brutes. Rasheth polishes their pillowfists and low mat a fair bit, as well as accentuating their resiliency. Also, with the move from killing things at range, the Cannoneers can actually get into positions to use their capable melee prowess (especially under Rasheth), so, you might not need a killy melee heavy when you have them, though out of theme they can't be in a relevant spot to charge in.

If you go with Sentries, then it's pretty much locking you out of utilizing the theme benefit of swift hunter. You won't have the points to include much more than a shaman/raider pair. They're a good pair of ranged beasts though. If you want to drop one cannoneer for a Shaman, then it'd let you free up some room too.

When I've been playing around with Winds of Death, I've come to the opinion that optimally, you start with max slingers, max Reivers + UA, Dakar, and 1 piece of artillery. This gets you to two free solos. For the free solos Marketh is usually the best bargain, and since a soulward is pretty much required I go with him, though if you're blessed with extra points go with a second Dakar or a willbreaker. Double Cannoneer and double brute is a good battle group, but Sentinels, Sentries, Raiders, and Shamans can all be worked in there in various combinations. Don't go with out two shield beasts, though. That's the main rule.

Lastly, there's another big issue with Winds of Death, the Dakar. He's got a weapon master gun, veteran leader to the only unit type our theme allows, and the theme simply isn't going to come into its own if you don't use him. The Reivers don't need him so much, so you can do two units of Reivers and not need him (but they are terrible against stealthed units), but the Slingers get quite good with the Dakar's help. Also, his boosts to artillery, the extra move and the reroll, are worth including a reiver cannon or catapult. Here I'd go with the catapult since with Rasheth and Dakar it can hit a heavy for a ton of damage.

His command leadship thing increases the rat of the reavers and the slingers.

max slingers, max Reivers + UA, and 2 Dakars gets you the same 2 free solos or artillery pieces for 1 less point.

x.x; lets all just admit that Winds of Death is more like Winds of Daft. The one thing skorne sucks at doing is killing things at range... the theme we get detriments our ability to fight at close range and supports... what? our artillery? Doesn't really do much else than what we already could do with the units it restricts x.x

I really think adding Siege animatrax to theme is a step in a right direction. They are fast (trample 11, shoot 12, reposition away), hit in melee like a heavy warjack (4 atacks ps 18, free charge) and have 35 boxes at standart 10/19 heavy stat line. In theme, when each of them gives you 4-5 points discount, I'll take them - they should return their points back easily.
