I have tried to use the new arc warlock melee aspect with the charged with light mod called "Heavy Handed". On use, it should consume one stack of charged with light to restore half my melee energy, but it doesn't even consume the stack on use. I have tested this multiple times and only managed to get half of my melee charge back once, so I presume that Heavy Handed should work with the new arc warlock aspect melee.
