I don't know what they should do with widowmaker. I just know I hate being double body shot so easily, so perhaps putting more emphasis on higher charge and less about spamming non-headshots... even then the great widowmakers can get pretty out of hand as well. I am bothered less by a really skilled widow who rarely misses a headshot, but when it comes to these great snipers the refire rate seems a bit too high. A miss, miss, headshot ouch.
There is a certain non-fun factor going on here as well, because even a widowmaker that is slamming a team might be contributing a lot less to an overall win than say a tracer who is putting out the same pain.
The SMG is actually quite weak. It's basically much weaker than s76's rifle. Much more spread and 4 damage per shot less. I think I was told overall it is ~40% less consistent dps or something. The SMG doesn't bother me at all.
It's 40% less compared to the main weapon of an assault character. Her secondary weapon. Meanwhile Hanzo has to contend with actual projectile movement (and fall) plus "reloading" after each shot. And he's pretty much dead in melee unless he gets a lucky shot. I think there's a problem here.
