^It doesn't nerf archers.
It only buffs people that want to use 2 handed swords when dehorsed who cares.
More important is the fact that many weapons fit .5, 1.5, 2.5 categories. This is also good for shield users who deserve more diverse pro's and cons to shields .5 or 1.5 slot shields would be awesome.
Another class that would benefit would be hoplites, some spears would fit this 1.5 slot category.
This idea would increase the diversity of secondaries available to much of the cRPG community and aid in specific class and weapon balance.
