Yeah, but it really has no effect in PvE. In PvP it disables enemy super and jump abilities. So being able to silence whoever from any distance would be a little overpowered, especially as a sniper. I gave the silence ability to the Solar Titan as a perk for the melee. Once the melee is used the target is pulled closer to the Titan, the suppression activates so it can be used against supers and further prevent escape.
