Give it time Solar, the BT's will make it to EC eventually, their exclusion being largely based on a limited number of chapter slots at release and that the BT chapter structure is quite different from the other SM chapters, I think we can all see why the Dev's decided to run with 4 standard chapters at release, since with the same chapter structure theres really no difference between them just a reskin issue to have them
I hope they do implement them eventually,I'm counting on it. I'm willing to wait as long as it needs to make them right but I don't want to rest on false hopes, once a game is usually made and profits come in devs move on to another project just as fast. If there is no demand or not a loud enough one for what the user wants they wont waste time on making stuff that people wont spend money on, So just cause theres a rumor they might be in it doesn't necessarily mean it'll happen, if you'd like to see them aswell speak your mind now while they are listening or forever hold your peace ^^
What do you guys think about changing chapters? You know someone will ask for it someday. I would say start a new character rather than allow chapter changes.
Devs have already said that when they bring in new chapters /races/factions existing characters will have an option to swap to them, I'm assuming it will be a one time deal for free and maybe a cash shop option might happen at some point as well
