I don't think we should ignore the unlock requirement, seeing as the new WSs are very easy to get, if a little time consuming.
As far as I can tell, in terms of strength it should go Skill WSs < Merit WSs < Quested WSs < Trials WSs. If this isn't the case then fine, but it seems many people just want the new WSs to be uber because they are new. That's what people mean by balance.
