"Maximum base charisma needed to gain the full benefits of the battlestyle rages has been lowered to 16 base charisma. The scaling works as before up to +3 modifier, but it now counts +3 as +4. Unmodified rage has not been adjusted."
For chosen of IIeval who use their intelligence instead of charisma as their rage modifier, having 16 base INT after perk adjustments gives +3 instead of the +4 as it should. I am currently only get 7/7 rage instead of the 8/8 rage.
