could be interesting,but wouldn't change much if the tanker can see the EMP in his fov flying towards him, though "close combat" EMP & throws from the side / behind / top etc. would become much more effective
Some players are incredibly good with throwing EMPs, others just..... fail.
some weeks ago I've seem Wiz. tossing an EMP towards a flame tank, which was trying to drive over him in full speed (flat ground). Wiz. managed to throw the EMP so that the flame tank was excactly in the middle of the blast radius when it detonated (ofc it's the tankers fault here, but still a nice EMP)
