A new talent for the Mechanic which allows them to "Fiddle" with mechanical devices to boost their performance for a short while. Boosting Engine speed, pump speed, weapon damage and fire rate ect, maybe even decreasing fabrication time.
For balancing we could make it deal damage to devices slowly while fiddling, and give it a cooldown, maybe 30 seconds, so you cant just sit on devices the entire day?
This would be a good new addition in my opinion because it would allow mechanics to have a more interactive experience, able to be called to action by the captain when they need to go fast, or help assist fabricating items faster to add to the cooperative feel of the game.
What do you think guys?
