I do agree that as it is now the weapons systems is relatively balanced. Or rather there isn't an ocean dividing things at least. I'm not sure about energy weapons at all so don't listen to me in that regard. I question the worries of grenades being overpowered, but I'm hopeful that it won't be a total catastrophe if they are changed.
"Small guns" typically means snipers in my experience. I don't think small guns bursters measure up well against the other weapons (The biggest advantage of small guns burster is that I don't need much SPECIAL/Skills, so I can easily invest those into other areas so i can taxi/craft, and its easier to craft ammo typically) But is that enough? Should things like that be considered, or should the end result in a straight combat fight be the only thing considered? They aren't useless and things can stay the same at least.
Sneak is one of those skills that if nerfed would be completely useless, if buffed completely overpowered, and the "balanced" range is a tiny little sliver. I think things are adequate for now, but I can't say that with much certainty.
Personally I just want to see balance in perks/traits, and then see some concentration on game content, then I would be happy.
