k. Just thought it would add even more depth to the gameplay. In low proflie you do the gentle push, walk at normal civilian speed and by pressing the weapon hand you can temporarily pretend you talking to a civilien (only for a short time as they would slap you or something) legs would do nothing and head would make you start acting like a herald or something like that. In medium it works like current low profile exept that off hand makes phisicalypush someone (not to hard but enough to push a few people back if your target sees you so it just seems like your in a rush to get some where). High profile works exacly the same as it does now.
