Heh a list would be a lot of work. Right now Iīm having too much fun playing the game in singleplayer to do that kind of work
.
I tried to replace the Mictlan hero you mentioned, but the replacement command didnīt seem to work and the hero could appear twice. Maybe itīs just because the hero is defined as hero4 or hero5(I only changed the first 3 since mictlan gets only 3 at most), but maybe it simply is not possible to remove official heroes via modding.
