Sett Q Does Less Damage than Regular Attack to Monsters

Set's Q is capped at 400 damage to monsters.

But if Sett builds AD items then his regular basic attacks can do more than 400 damage... so using Q actually REDUCES your damage. Example:

Regular auto left: 450 damage (only 400 with Q) Regular auto right: 550 damage (only 400 with Q)

Maybe this should be coded to cap the Q bonus damage instead of total Q damage because reducing damage by using Q is likely not intended.
