Grim Hollow Feat "Lightning Caster"

Quote from MyDudeicus >>

why, there is no RAW and if i were to allow this feat which I wouldn't I'd let it work equally for a wizard as it does a warlock an entire cantrip of damage on a both targets. Warlocks give up a absolute crap ton of casting power to be the best cantrip slinger out there, a single feat letting a wizard trump them in their specialty does not sit well with me. 

Not all options need to be equally optimal for all classes.

There is a difference imo between just not equally optimal and one feat letting a class trump another class in its specialty.

Which this doesn't do.
