I like this idea , but there is something I do not like and I feel like it should be changed to :
Getting in the way of the T and the CT which is dueled should not be allowed , yes the other CT's can get killed easier but blocking the view or let's say a door can waste a bullet in shot 4 shot , or a swimming race , getting in the way would block the person and therefore will lose , yes I have read that CT's are not allowed to attack back but still every shot is vital.
Just my opinion , everything else seems good.
