I want to say yes we are still supporting tribes. Although currently we dont have enough grunts to do so (within the rules). You need three active members for a tribe to be legit. but currently the biggest tribes only have two. Still these tribes do have supporters, leaders, and are part of the history of the BC so I personally dont want to end them. I do think however we should make sections for these tribes like we used to have,this way we can see which tribes are active/inactive and what they are all about and it wont hurt our history with tribes at all.
We may have to revert all Grunts back to tribless and then let them figure out where they want to join/create with the remaining Grunts.
