That's fine, but I think it's essential to add the Hexblade for melee warlocks. Then they can utilize charisma for their melee weapon attacks. The sub-class utterly overpowered, and a no-brainer one level dip for any character that uses Charisma, but it is what it is.
I definitely want Hexblades, but Wyll is alerady a Fiend Warlock and his personal story seems to be reliant on that. So I'd very much like to see his stats be usable as a Fiend Bladelock, even if it has to be done with Standard Array.
