With the release of the Arbites are we going to have at least a new character slot ? Through the years i’ve made a character for each slots, and i’ve grown to like everyone of them. So, now i don’t see myself deleting anyone of them honestly. 
Yes, confirmed by CM Kitefin in the announcement thread.
Only thing we don’t know for sure is how it will affect modded users who have filled up all 8 slots they can unlock.
How can so many people be so concerned about this topic yet not enough to see it’s already been answered in the announcement post?
