I’ll raise another problem for heavies, different than what we were talking about, but still on topic… I don’t understand the heavy weapons perk nerf. The 30% to 20% thing is ok, it could even go to 10%. However, -20 perception is just too much. If it was hearing range, ok, but the guy becomes just blind. His overwatch ability is almost gone, and thus it doesn’t make sense to me to get this perk anymore, unless you also get the other one that gives +10 perception.
Besides the perk overhaul we’ve been talking about which is farther away… I think this specific nerf needs to be changed… I would rather get +10% dmg/aim and -10 perception/hearing range. Hearing range even makes sense, the guy trained so much with heavy weapons and explosives that he can’t hear well anymore 
It could also be +20 or +30% for accuracy only, would do wonders. Heavy weapons don’t need +dmg anyway. I’m not sure if this value affects only heavy weapons or all weapons though… I’ve even raised a canny ticket about these descriptions being dubious.
