Zones I went right into sharper blades tech. I wanted to beef up skeleton legion so they could be dangerous in the early game, and it seems to have worked really well.
I don't know what all the hubbub was about, Undead is so easy and fun to play. I just completely skip the caragous and the rest of their army is really good. The light armor tech buffs so many units, highly worth it.
Not having to carry farms and farm workers is SUCH a big help, makes it easy to load up on mines, mills, guard houses and homes, without feeling like it's stretched too thin. I sent out an attack and wallahhhh didn't have to worry about food going crazy. I think I have like 0.3:1 farms and am overproducing food easily with 4:1 homes. It's crazy.
If anything Undead might be OP, we'll see as the mini round progresses and I get heavier units produced to take over from skeletons.
