Came here to post to same issue. Summoned the Pyre of Men 6 different times and all it ever did was get used for swarm bonuses then died.

Like lots of other people said, I use Warden and High Tower quite often, usually on the same outpost. I never looked at stables but I imagine I'll start using them on unit hubs now. Caltroops seem silly since enemies can just counter the outposts. The offensive and defense upgrades seem OP and slightly cheesy to be honest because I believe they provide an even higher boost then being stationed in a city would? Never really looked into the extra growth optio
LOVE shadow world and blood curse. I feel so powerful just thinking about them o.o
300 turns, no crashes. I'm so happy :D (the AI is still kinda easy though...)
When I berserked (the spell) a group (8) of soldiers with leather armor and spears, it gained like 400 attack.
