What's the reason updating Attrition skill to level 20 when never can be reached the 60% bonus!

For Ranger builds is impossible to stay more than 30 sec in presence radius of Boss. Presense radius needs some Lineage support couse passive tree nodes isn't enough. For melee builds is easier due to the close combat mechanism but even then is very hard to reach max bonus.

Please change the ratio to half of the current bonus. 1% more damage per 1 sec with max limit (30% more damage) is a perfect ratio to satisfy both ranged and melee classes.
