IF you are ever prone, and you have infected chasing you, they can go on top of you, and make it very hard for you to fight back, get up, and causes unnecessary player lag. It's very easy for them to just step on top of you, and you have to start moving.rolling around, until you can get up.

Players can also do this, they can very easily just step on top of you, and the same problems happen. When attacking animals like chicken, you can also step right over them when trying to melee them.

Infected should not be able to go and step on top of you to start hitting you, they should always be right next to you, not on top. Same with Players, unless they jump on top of you, should not be able to walk/step right onto you. It just causes a bunch of lag, problems, and frustration at times, and can get you killed.
