But that's fun to do. I'll admit I've done that a few times after hearing about it lol.
Fun? Not for the receiver, but yes for the user
Cheap=No... Effective?.....sometimes.....you can easily go prone or crouch even when shock charged next to a BB
Shock charges are fine. The only time they are a problem is when dropped right next to a BB
And waste two points in doing so. Better off with a Claymore.
The nerfs that you suggested would make the shock charges pointless. If you don't want to be affected by them then just run Tac Mask. You'll hardly know that they are even there.
