Except if you don't aim with flashes and stuns you won't be able to get the proper effect. A stun or flash that lands further away has less of an effect on the enemy player. An EMP grenade that lands 500000 feet away from the player EMPs them, period. Even if the player is on the second floor of a building and you throw an EMP that lands outside the house.
No, the range is completely different given distance to enemy player + effect on player.
As I mentioned earlier, stuns and flashes that land far away = less effect on player. If you're going to allow EMPs to hit through 2 buses, or a whole house, then it should effect you based on range/distance to enemy/affected player.
Now this i call bs, yeah if you throw it at a wall and the guy is behind that was it will affect them, but if your on the 2nd floor and someone throws it below you it doesn't effect you, stop, you sound like a little kid looking for attention.
