Rogues in Legion have two talents that increase their max combo points, both on the same tier.

One is Deeper Stratagem, which increases the max to 6. The other is Anticipation, which was modified from it's live form of using charges, to in Legion, increasing your max CP to 8 not 9.

I have confirmed this on alpha that if I do

/dump UnitPowerMax("player", SPELL_POWER_COMBO_POINTS)

the result will be 6 with Deeper Stratagem and 8 with Anticipation


It's possible that there is another way of getting that one additional CP, but honestly I think this is just a miscommunication between the class team and the UI team.


edit: In Blizzard_NamePlates/Blizzard_ClassNameplateBar_RogueDruid.lua they have this:

if (maxComboPoints == 6) then
    self.maxUsablePoints = 6;
    self.Combo6:SetSize(self.comboPointSize, self.comboPointSize);
    self.Combo6.Point:SetSize(self.comboPointSize, self.comboPointSize);
    self.Combo6:ClearAllPoints();
    self.Combo6:SetPoint("LEFT", self.ComboPoints[5], "RIGHT", 4, 0);
    self:SetHeight(self.comboPointSize);
    self.Combo6.Background:Show();
elseif (maxComboPoints == 8) then
    self.Combo6:SetSize(self.bonusPointSize, self.bonusPointSize);
    self.Combo6.Point:SetSize(self.bonusPointSize, self.bonusPointSize);
    self.Combo6:ClearAllPoints();
    self.Combo6:SetPoint("BOTTOM", -14, -2);
    self:SetHeight(22);
end

The accompanying xml file has 8 combo point widgets. It's very likely that your example is just a typo
