I think it is pretty well known that reavers do not work when trying to push into someone's base. If you build in a certain way, a reaver cannot shoot something that is clearly in front of them. I am making this poll to get an idea if anyone else agrees or thinks it's a balance against PvZ or PvT. I have seen on some videos where pathing can be done incorrectly causing reavers to not be able to shoot. I think it can be fixed but I am not entirely sure.
Either way, good luck have fun!
