Please tell me how I an improve it. I want it to be good but balanced so feedback is appreciated.

No no no, your idea is great. But a while ago, I saw an idea revolving around magnetism, and redirecting/deflecting bullets that I liked a tiny bit better. If you want it here it is... SUPER: magnetic field The user creates a medium sized zone around them that catches all bullets. Enemies trapped in the zone will be slowed and disoriented. The user can move freely and the zone will follow him. Last as long as arcblade. Upgrade 1 Redirect All munitions trapped in the field will be flung back at the one who fired it for slightly less damage Upgrade 2 electro storm All enemies caught in the field will get stuck, float up and suffer from an EMP that disabled all abilities. Upgrade 3 swift movement The user may sprint at double the speed and will dash forwards on a jump to try and catch people in the field Grenade Grenade 1 electronic field Creates a magnetic field where the grenade lands (AoE) Grenade 2 conductor A sticky grenade that electrocutes target until death. If it misses, lets of a pulse of energy (sticky) Grenade 3 shockwave Grenade magnetizes targets and sends them flying back (like incendiary) Melee: Lightning bolt (think throwing knife) User fires a blast of electricity at a target from a distance to take them to half health Upgrade 1 chain lightning A kill with lightning bolt chains the blast onto a nearby target Upgrade 2 charged Targets hit with lighting bolt will become charged, and will explode on their next death, whenever it happens Upgrade 3 precision Precision hits trigger a blast of smaller lightning bolts, and damage the target even more (3/4) Jump Glide, blink... I don't remember the rest of the upgrades except for self magnetism, which let's you levitate when you are effected by a magnetic field from a grenade

That's quite good actually. My only issue with that is that if they activate their super in PVP they are literally invincible.
