I agree elf and dwarf races are inferior to human undead, and so much harder to keep alive for no loss, (elf have only faun to resurrect and only plants-thx so much developers wtf am i suposed to do about my archers,unicorns and hordes of fairies in my army, dwarfs are even worse only droids can be kept alive).
Races in game arent balanced, but game have so much potential and with some good ideas, and spare time it all can be moded to interesting situations
(my problem is stupid buged editor that crashes every time i try to eidt some item in it, so i ask other ppl to do it for me
As for more reserve slots, check this tread pcbun add it in his mode, so either PM him, or check his mod files and try to figure it out
