i gues best would be 'ckit' version not normal equipment... due to human advantage in ranged armoury for me...
ckit should use alt to shot 'target' position and again teleport back to that place 

 that 'position' thing should be throwed like shotgun alt (tremx)
that would be realy nasty 

this should be funny for granger 2 

 or dretch... alt + dig in ground 

 that can be get out only with flamer or grenade 
 but this is only an idea
