Buying skeletons and equipment is more expensive thanzombies, but we already have the equipment so we can use it on skeletons.
Or we convert equipment into DP. We are not losing anything, equipment is converted to its full cost.
Captain Bonesessesse also buff skeletons, but not anything else.
We have enough skeletons to buff
We also don't know if zombies get upgraded eventually, but we do know that skeletons do.
I don't expect that enough meatshield skeletons will survive to get upgraded
So I think that we should keep using skeletons.
I don't mind buying X skeleton+rusty sword for meatshield purposes. It costs 10 DP and and I believe it is more cost effective than Skeleton+spear+shield.
My current plan will give us such high quality units;
a) Capitan bones - Him and his equipment costs no less than 50 DPs
b) His two spear+shield comrades in leather armor cost 25+ DPs
c) One new greatsword skeleton costs at least 25 DP
d) 4 archers, with one being somewhat inferior. Their equipment alone costs 20DP
e) Emperor bat
f) Attack mage
h) Ninjaskeleton(c)
+ we have 8 low level units (bats)
We need some cannon fodder cheap units and I see three options.
1) Skeleton + rusty sword = (10 DP)
2) More bats (10 DP)
3) Zombies (5 DP)
I prefer to make the decision after we will get a core high quality army.
