Interesting Ideas I would Love. Please add to this.

[CKNovel]

Thanks for ruining a fun post by destroying it. Considering the fact everything mentioned is do able.

Because it seems good to you doesn't means it's good for everyone. You have ideas that does not change a things like PVP and Hume/Dwarves/Mystel races.
Then you have the idea of adding Garlemald race except it goes against the lore. Would you lock mages out of these races?
Just your cross-over ideas are purely based on your tastes.

What if I want to have an Arknight collab, a Berserk collab or a League of Legends collab?
Because I and others could enjoy it doesn't means everyone would. Nier has been a good example.
