The problem with balance discussion is that at some point people are going to turn a mosquito into a horse. 1.15x damage means that you need to apply that damage 6-7 times to get what is essentially an extra hit worth of damage, and 1.25x is 4 times. It's not that much of a damage improvement, given that slowing effects are rare and incapacitations break after only one hit. If anything the only rear non-conditional buff is for acid pistols because they tend to root with every shot, but that's it, everything else you need to apply that debilitation by throwing nets, stunning with tasers, throwing flashbangs etc
