and maybe: allow us to get more than 1 single source from corpses/enemies at a time :^/
also its VERY annoying that i can seemingly only use source vampirism on a few specific enemies AND i need those enemies to not have magic armor(read: if u run on a party that deals mainly physical dmg, u'll rely on consuming corpses :^/)
...doesnt help that in the late game nearly every enemy seems to have source vampirism, and player characters tend to have WAYYY less magic armor compared to enemy NPCs(and unless u have like 35+ wits, they'll get 1st move, wiping ur magic armor), so they'll constantly be stealing ur precious source
anyways, the way source points are so rare(especially before act 2) gives source skills a very bad "too good to use" problem, and in many cases, a "not worth using" issue cause many source skills can be VERY lackluster compared to others with equal/similar cost
