The fact you put in brackets "nearly too well" shows that you are aware, and "too well" is the same as "overpowered" in a game sense of matter, all I'm asking for you is to acknowledge its overpowered. - And I understand you asked it as a question somewhat, but the fact you feel the need to ask in itself is a joke and I think you already know.
It is overpowered if it can stop 70 people pushing, 7 people, stopping 70. Anything that allows this is broken and needs adjustment, that's plain simple and obvious.
