• Nerf the damage and rate of fire.
• Give it HP and make it destructible, but remove the duration and lower the cooldown greatly so that it becomes a 'companion' summon instead of just some sort of dot spell which it essentially is at the moment.
• Every available Charge increases its AS, and every Charge you lack increases its MS.
0 Charges = +50% MS , +0% AS
1 Charge = +40% MS , +10% AS
2 Charges = +30% MS , +20% AS
3 Charges = +20% MS, +30% AS
4 Charges = +10% MS, +40% AS
5 Charges = +0% MS, +50% AS
• GunBot has an inherent % chance to Flee when hit
As far as I've noticed, it might even be untargetable like Heal Bot.
