The radius of the emp in comparance with the tubes or grenades is indeed a lot less, and on cars they do not work at all in my opinion. If an emp falls a little bit away from the bubble it does not defrost, where a tube hits the other side of the wall and it kills you, a little bit overreacted in my opinion. They are way overpowered. Never in the 8-9 years that i am playing here has the Tubes been this overpowered and indeed in some maps ruining the fun for a decent game of Freezetag. 90% is using them now. Aiming and shooting will soon be something of the past. Also want to add that my predator is often (approx. 70%) of the time not killing enemies. I drop them near them, like right behind or infront and all i see is an X and nothing happens, also weird stuff.
