Black Templars are a small test bed of some of the possible changes in the future. Players will note that in the Space Marine roster selection screen, you will see Black Templars and Black Templars V2. The V2 files have had several squads redesigned to allow models which change the basic profile to be selected as separate models. This allows the profile for a model to be clearly defined such as in the case of a power fist (with doubled St, lowered In, and of course no bonus attacks unless you happen to be armed with two power fists) or even just a Bolt Pistol and CCW (with a different attack profile from a model with just a bolter). This is mainly to test the feasibility and player like/hatred to such a design. Note that what you gain in clarity, you make the sacrifice in roster pages.
