Many people have expressed their displeasure with the changes to fusions but I'll put my own flavor to it.
So IMHO (as well as my son's and Daughter's who play) fusions were 'almost' perfect before. Our reasoning is this:
We considered Fusions the weapon of choice for the quick kills that are just beyond Shotgun effective range.
They took a degree of skill and timing that I feel even surpasses sniping. You needed to know your charge rates, dispersal, and effective range. Frankly the only people that you saw using fusions were people who were exceptional with then and they Rekt with them. It was respectable though. You didn't have a lot of people running around with them (al la Shotguns) so I feel that in and of itself balanced the use of the weapon.
The change to the stability has made them a much less friendly weapon to use so now even less people will use them and even the ones that do will be less effective.
Please reconsider the change.
