They won't be though, As pg 63 says;
If they are in a single unit, the Pladins will all share the same profile. Other than when an independent character joining the unit, Paladins won't have any characters other than an Apothecary. So at most he will be more survavible, but you will simply result in killing off the next nearest Paladin in the unit. The old system meant you could would all of them before killing any potentially. Now in any given shooting phase you are much more likely to kill one or two off, and if not the GK player has to cycle them to the back of the unit, reducing the overall movement of the squad, making them less effective (especially if you just wounded the Incnerator!)They have their own profile, but do not have a separate entry.
Having played a game, this system did seem a bit alein and complicated at first, but we were quickly working out casualties much quicker than we had been under the old system; well compared to when you had units with at least 3 different wound allocation groups before anyway. Less is about the same.
