My question is about the Electro. You use the left mouse button and it shoots a ball. You use the right mouse button and it spills out a lot of balls. After you spill out a lot of balls you can shoot a single shot at the cluster with the left mouse button and it makes a large blast. I have been playing this game for a while and I have seen people make a large blast without spilling out a lot of balls and shooting at them. I have yet to figure this out. My question is: How is this done? Are they cheating?

There was a recent bug with the particle system on one server that could be mistaken for this.

Remember the balls can also be detonated with other things such as the laser, grenades, rockets etc.

Most of the time I tend to use the electro by just spitting out 1/2 balls then detonating them to keep it fast.

also keep in mind you can set off other ppls electo balls too (if you have the electro and shoot em w primary) . as for cheating, no.
