The Aventurine team has been teasing the Areas of Influence feature for a few days on its Facebook page, but next week's patch will put it in the game. The Area of Influence is an expanded bit of land that's attached to each capturable control point. These areas show up on the map and offer a set of stackable buffs to the clan members and allies that control the area.
Read through the forum post for complete info on the addition.
[Thanks for the tip, Dengar!]
