a)No, I didn't change it, in my versions there were Zombie Knights riding Nightmares and Skeleton Knights doing the same(actually I used cheats to check the full tree).LazySteve said:They are upgrade-able because YOU changed the code, at most times, like Nosture said, they are just fodder that clogs up your party space, try fighting any lord (of the regular factions aswell) with just 250 zombies/skeletons, they will just get trampled in seconds.
Secondly, making such a complicated class system might be easy on paper but it's actually a very hard, complicated process, so you can't expect guspav to just start a process like that based on 1 person's comment
(P.s. the DeathBlow sounds useless, when was ever a battle decided by you killing a single guy? (and almost killing yourself in the process))
b)guspav is most likely to do that for two reasons:
1-He said he wanted a class system
2-This is based heavily on Dungeons&Dragons, but also in Heroes of Might&Magic III and Forgotten Realms, and all three of them have Class Systems.
c)Then we may make Death Blow(this is a theory only), an automatic feature that, does not consume health, and, the higher the Death Knight level, the more often it occurs. Let's say starts with 5% possibility to occur and each level increases it with 1%. Either with a dice roll(like classic D&D). But I feel it must be in.
