I cant see where the buff is when guards could only get 2 ptrs OR 2 dps instead 2 ptrs AND 2 dps?
If you don't see that guards would have to go down in cost or ptrs up in potency and DPs up in potency, then you don't know how balance works or what it even is.
It would also make guards much more mobile and significantly decrease chance of weapon drops.
It is also a dead horse we have talked about in year 1, when people still remembered how campaign Guards worked and these campaign guards would be your new guards as otherwise they would be severely underpowered.
