The issue for me are usally the last names, as it is difficult to mess up the first name. Some examples:
o) Marius Leitdorf = fine with me
o) Aldebrand Ludenhof = (Erich) Ludendorff comes to my mind, which is not so great, as I don't really want to be reminded of real (historical) persons. Otherwise an ok attempt, as I like the first name (sounds noble and old).
o) Boris Todbringer = that's not a proper family name, but a byname at best. Boris Propername, "Der Todbringer" (The Bringer of Death)
o) Pieter Verstohlen (A spy from a BL novel) = No ... just no. (verstohlen translates to something like surreptitious, perfidious.)
A warhammer pundit will always enjoy a finespun wordplay - as long as it is in good taste and moderation.
But how often is that the case?
