@CarpenterPack08 A couple issues.
Shockwave: Not a shockwave, but a cone.
Arc Cone: 75 damage, 0.5 second stun like arc stars, disables vehicles (Trident) for 3 seconds.
3 second stun is free multi kill and too powerful.
Using the Ult to cast shockwave is too much.
There are only 4 fence charges and it takes about 15 seconds to charge, therefore once every 60 seconds you can cast the Arc Cone. That's not too OP.
Alternatively, mobile Pylon. Arc Blast and Mobile Pylon could be upgrade options, and you only get one or the other.
Because, if you get both, then you'd be OP, chasing people while casting Arc Blast every few seconds.
Now, here's a balancing idea for arc blast, it have a charge time before it blasts, then people would have an escape chance or chance to run around a corner.
Now, Pylon+Blast would still be OP, but you'd be limited to the radius of the Pylon, probably within line of sight to it, to recieve its swift charge boost. Small area. Coupled with cast time makes it more balanced.
Both effects would be nice though.
