A skill that adds +n damage adds more damage when used in the support position than the active position, because the support position gets roughly twice as many strikes.
A damage proc skill adds more damage when used in the active position than the support position, because damage proc skills only activate in the active position.
It is therefore fundamentally impossible to have a test that
1. compares a +n damage skill against a damage proc skill;
2. is biased against neither the +n damage skill nor the damage proc skill; and
3. satisfies the 1 independent variable control criterion.
This comparison favors Aether over Aggressor because
1. Aggressor is a +n damage skill and wants to be on the support position;
2. Aether is a damage proc skill that wants to be on the active position; and
3. the comparison assumes the active position.
