Yes, I know that his basic only does damage to 1 target. Yes, I am sure I used the basic attack. Yet still, dodge animations occured over 2 of the 3 debuffed enemies as well as the enemy that was attacked. It appears the calculation for the extra damage on the basic acts like an attack on each debuffed enemy, which can be dodged. If I am correct, not only does it have negative consequences when facing evasion teams, but it can also lower his damage when any enemy dodges these bonus damage "attack" calculations. It would harder to notice in those instances.
