Going through the weapon tables from the manual, just noticed one thing:
The legendary blunt weapons are objectively significantly better than its edged counterparts. That is, while they seem nearly completely identical, given the much higher weight given to edged attacks in opposition to blunt attacks, and that the legendary attacks not only have superior stats over all but also are always edged, making so that legendary blunt weapons nearly always pick the the legendary attacks, unlike the legendary edged weapons that still have a fair chance of picking the "merely" good normal attacks.
A quick look over in Arena mode does seem to indicate that it is such, with the legendary attacks having a rather high statistical weight. Nearly all attacks with the supposedly blunt weapon (strangely enough, the dwarf seems to enjoy a bit too much using their hands instead of their weapons o.O ) goes over the legendary strike, with "Righteous Angry of Sigmar" this and "Holy Wrath of Sigmar" that.
While it's not a big problem in itself, specially given that Legendary weapons are supposed to be legendary and all that, but it does create two problems: Boring combat logs with little variety, and an imbalance between the legendary weapons, with blunt weapons being objectively better than the normal ones.
