There have been some changes to the way Close combat weapons work for Tyranids. The rule used to be, that Scything talons were the only CC weapon that would give a +1 Attack bonus. Now it applies to all Tyranid CC weapons, but only when 2 pairs are used (basically a shift of where +1 attack bonuses will be in the Tyranid army for the CC Monstrous Creatures, and medium sized models with 4 arms)
Previously, the attacks were already reflected in Tyranid profiles. I am wondering, with a new rule change, if this is still true.
If it is NOT reflected, then that would mean the Death Leaper is actually 5 attacks, and the Carnifex is actually 4 attacks using their basic set of weapons.
