While such ideas are great, and imagination is nice...
I am pretty sure the devs are already pretty packed with content to implementent until release, and even some things for afterwards... Maybe they even have something like this already in mind 
While we can fantasize, I wonder if big systems actually have any way into the game

Another example, A missionare guild does agressive racist fights between other guilds or attack towns.
"racist fights between other guilds"
Only demons can raid towns, and I think also only human towns?!? Sieges between guilds are always between two guilds of the same planet. So we would already have different guild types for the different planets (not races).
@memokal said in Guild Types:
In addition there maybe bandit guilds that attack people randomly. And they be deserted from other towns so they create a bandit town for themselves
Yeah, a bandit town instead of a normal town, which good aligned people canยดt enter / is hostile against. Sounds fun 
Now this depends on PvE and PvP to both be present to work... So on Tartaros, a very PvP focused Planet, there will probably only be one guild type? On Arboreos I think it would be the same
But for the Human planet, there is a lot we could fantasize about
