That's weird, I inserted your name and suddenly couldn't type anything else in, and it wouldn't go away no matter what I did.
Anyway, I agree, the Bloodseeker Palanquin is uninspiring. So I'll move on to another topic, but if anyone else wants to share any thoughts on this thing, please do.
So the next thing I've been thinking about is... allies!
What allies have you used to give you some kind of advantage that we don't get on our own? Personally I think I'm on the same page as @discoking with how Soulblight really works best - be good at moving fast and punching hard. Other fripperies only dillute that strength. But still it can be fun and useful to try some outside stuff out. Here are the things I have in mind myself.
1) Dire Wolves. Cheap, durable and reasonably quick. Almost everything in Soulblight costs some multiple of 80 points so it's good to have these as a way to fill out lesser remains. And I think a bigger pack can have a place too, bringing plenty of wounds for cheap.
2) Corpse Cart. Pretty weak but it's cheap and has an 18'' bubble for either giving you +1 to cast or giving the enemy -1. I've tried it and it can hold a home objective decently and the bubble is usually big enough to effect something worthwhile.
3) Mortis Engine. Pretty much a Corpse Cart +1, for a lot more points. Fast enough to hang with the rest of the army and gives some cool bonuses. Never tried it myself.
Fill in with what stories of allies to Soulblight you might have!
