This is a pretty comprehensive weapon change and it will probably require more balance iterations in upcoming patches. The goal is to shore up some weapons that have been forgotten or lost to time and to pull back some weapons that have been dominant in the meta for too long and reduce some more oppressive ranged archetypes in quickplay.
