You're welcome to read the explanation in previous posts. Plasma's were doing better dps than Avengers, Frags were being used to keep people down for long periods without being able to respond. Both of those things are not allowed to happen.
Frags will get more splash and a slight boost (aswell as armour being changed around). Plasmas will get a boost up to ~+35% not the old +50% and will not make you burn a trait to do so.
I don't want heavy weapons to be the ideal sneaking weapon. Throwing, Pistols and Melee will be advantaged as far as sneak is concearned, heavy weapons will be disadvantaged.
assault rifle, fn fals, tommy gun, greased smg, all shotguns
Plenty of other weapons have recieved the same boost. Plenty of weapons will get another boost, either directly or through the new perks. If those boosts don't result in the overall weapon useage being how I want it, I'll change more things again.
Eventually we will have diverse characters and multiple weapons used, as well as low tech weapons not being totally useless compared to the top tier.
