I would love if necromancy would work differently on undead - like I would normally expect - x% of dead enemy # in conjuction with y% of dead enemy HP (or leadership) is transformed after battle into one pre-set undead stack (based on necromancy level) - on basic you could choose from skells/zombies, on level 2 would be ghosts and vamps added on level 3 dark knights and necromancers ... + special artifact you could also select bone dragon. + the ammount of max Leadership of gained units will raise with your level

It would work like : with the same skill but on level 5 you would be able to raise one vampire and 0,6 of necromancer... but on 30 level 5 vampires or 3 necromancers...

for the "regaining" of lost units - I would use other skill, (if there is spell called ressurection, than the skill name would be tricky to find) but still I would like to have it the other way around :
instead of % - I would like to have Leadership of replenishable lost units.
If it would be 2000 Leadership - you would be able to regain after each battle either 80 archers or one green dragon (where one should be able to choose if he would like to go for specific unit, strongest/weakest, or random)
