The Dizzy Nade Debuff

many people know that there is a chance to get a dizzy nade from z-demo but i think its to op because your preaty much dead since your immobilized for at least 5 seconds while zombies are smacking you which could even cause a full iron with full food to die
not just that but it could also get people kicked for flying which inset fair
i think you should debuff dizzy nades or just not alow zombies to have them
