With rework of brutality and determination this will change in coming patches, last i read on ruforum people wanted to test more proficiency.
now thats interesting
what will change and how? can you tell us? (or at least link to the topic in ru forum pls)
They changed how Brutality works. As of right now and until 6.0.1, damage bonus from Brutality is calculated as if all the spells that are still flying towards the target already have done their damage, even though they did not. With 6.0.1 the actual, current HP of the target is used for the purpose of this calculation.
How hard your class is nerfed by this is directly proportional to how many travel time and how many burst damage abilities it has.
About Determination I have no idea what's changed.
