Here is my proposition to improve the brutality tree.
Gift of brutality : 25% chance on hit to improve autoattack haste by 25% and auto attack damage by 25% for 5 s
Unstable convulsions now has 100% chance to remove one blessing or enchantment from your target and to deal 156 damage (value with zero point in tree) for each blessing or enchantment removed
Mouth of tzeentch : now work with gift of brutality.
Convulsive slashing : increase the damage of the skill by 25%.
Touch of instability damage type change to physical.
Touch of rot damage type change to physical
Piercing bite armor ignore work on auto attack.
