I've heard these "confirmations" before, like bionics supposed to be cheaper than level-ups.
I mean, they retract the profiles for the sword and whip, but had no problems adding additional complexity to bionics for the least important injuries.
If Blood Bowl is anything to measure from, there's currently almost 90 star players and 140 special play cards. Several themes are re-occurring like Weather Mage, which is found as a card, an even and a limited winter bowl inducement. All with different rules, but basically doing the same thing.
And talk about complexity, precognition is a 3+ invulnerable save against non-blast non-template hits. Compare that to the second benefit:
Additionally, a Familiar may avoid being caught by a Blast or Flame template. If a Familiar is caught under a Blast marker or Flame template, the attacker should roll a D6. On a 4-6, the Familiar is hit by the attack. On a -13, the Familiar is able to dodge clear of the area of the attack. Leave the model where it is and assume that it has scuttled around to avoid the attack and returned to where it was.
Alternatively, you could summarize it like this:
4+ invulnerable save when hit by blast and template.
And then people would be pulling apart the rules talking about if a model was "hit" by a template and asking if it needs to dodge outside of the template I guarantee!
