overweighted Automatic Rigging Issues Greeting fellow Artist. 
i'm having trouble with automatic weight rigging. the mesh is a simple humanoid character. the bone is overweighted and effecting the vertex i don't want to(like shown in image). 




i know i can always manually weight paint it or re-assign the vertex group. but that defeat the purpose of "automatic" rigging don't you think??

what i wanted to ask is : is there someway so that my device can understand what i needed just by clicking the "set parent with automatic weight" without further weight painting. 
like any parameter i should change before assigning parent or any other way?

thanks in advance. sorry for bad english
Well, that's a normal behaviour. You can either add a bone to control the Neck part as WhovianBron3 suggested, or you manually fix it. The reason this happens is because the bone has high effect on this part of mesh because it is close enough to it.
