I'm currently planning out what skills I'd like my science bridge officers to have, and I like what I'm hearing about Hazard Emitters - it repairs hull and removes fire and radiation DoTs. I'm especially in love with repairing the hull because I'm an Engineering captain, one of my engineer bridge officers has Engineering Team, and I like the idea of combining both Engineering Team and Hazard Emitters together to take a severely damaged ship back up to full health in an instant.
But I've never actually used Hazard Emitters before. Is the amount of hull damage it repairs comparable to Engineering Team 1? Are there any noticable differences between Hazard Emitters 1 and 2?
