The problem people have with Billy.
I think the biggest problem people have with billy is is extreme map pressure
Billy is the only killer that can zoom from one side of the map after hooking a survivor to the other sized to kick a gen and back to tunnel.
I expect this to be even stronger with the new ruin coming out.
(in no way am I calling for billy to be gutted I am just stating as to why I think some people have a problem with him so please dont storm my house with your torches and pick forks)
