4.1 patchnotes:
The Focused Assault and Brutal Assault buffs have changed.
After 3 minutes of both teams having the flag, both flag carriers will get Focused Assault, which increases damage taken by 10%.
Every minute afterward, an additional stack will be applied to increase damage taken by an additional 10%.
After 7 minutes, Brutal Assault will be applied in place of Focused Assault. In additional to the damage debuff, this debuff also caps the player's movement speed at 100%. The damage taken debuff works the same and will add 10% to the debuff up to a maximum of 100% damage taken.
