Do they add in quicken later in the path?
And second, rather than invest fully in concentration, there should at least be a skill investment in intimidate. After all, the goal of a paladin is to confront their foes and smite them with the power of their deity, so intimidate should be a primary skill to invest in. If you add 2 points in intelligence(from say, lowering the wisdom score), I would suggest either making repair a class skill for a bladeforged and putting skill points in there or investing in concentration if you so desire. But bottom line: Bladeforged should have skill points in intimidate, NOT concentration.
