So, I tested out the Leto.
The Leto itself is...partially interesting.
In a sense that the default loadout itself shows, it can do support, a bit of firepower, but mainly harassment, and the drones show this.
The drones are very lackluster in forepower, can't scratch a Cerberus up enough to destroy them outright within moments, unlike a Terminator Drone, which has near to no difficulty in doing so. They can disable it's weapons, but struggle with firepower.
Meaning it'll struggle to fend for itself with anything that can get close enough to deal moderate amounts of damage to the shields and keep pressure.
It excels at using it's drones as a pest, but I feel that the system could be something else, like a hybrid between Targeting Feed and High Energy Focus, at the cost of some defense. I feel Recall Device just doesn't fit with the Leto, unless the drones were more powerful and relied on ammo.
