Top 5 energy drones?

Help

[Owlton]

I only know 3 which I'm certain is good:
1. Rail Gun
2. Unreliable Guardian
3. Unreliable Protector

When it comes to 2nd and 1st place it depends on the build, really

[hasn]

1.rail gun:high damage no backfire high drain (108) downside:limited range

2.unrealibe gaurdian:highest damage and highest drain (115) downside:high backfire so unrealibe protector is more preferred 

3.unrealibe protector:simlair to unrealibe guardian high damaging nice drain (84) downside:small backfire 

4.windforge: great 97 energy drain lightweight downside:not perfect for damaging builds so the other drones are more preferred 

5.face shocker: nice 95 energy drain downside:3 limited uses so you need to reactivate it
