Title wasn't enough for "Rather not-game-affecting suggestions" so I had to pick. So I had a few in mind,
* Changing the sound Avatar uses. Honestly, this is weird when some random beast yells "For Khaz Modan" while that guy itself has nothing to do. Howl of Terror sounds would work, if not I'm willing to search for one.
* Demon Lord sound set change to "HeroCrpytLord". I like this hero model A LOT, but the sound set is really annoying and IMO it doesn't fit the might of the hero itself. It's the soundset of a crypt fiend :8
* Alchemist hero from int tavern should really (I mean, really) not use the soundset of an Elven WORKER... His own soundsets should be fine, really.
[EDIT] : Added a new suggestion.
I had a few more in mind but I forgot
I'll be sure to post them when I remember.
