After thinking for a bit about a new Ensign level BOff power, and watching some DS9, I give you the Modulated Tractor Beam from the DS9 Episode, The Way of the Warrior parts 1 and 2, the first 2 episodes of Season 4.
In this episode, Worf uses the tractor beam on a Vor'cha to "deflect the Klingons disruptor fire". Roughly translated into STO terms, it could be used to degrade the accuracy of the targeted ship so you or whoever else gets shot up less.
My idea is that it does just that, and doesn't have the standard Tractor Beam effect, as the Vor'cha's movement seemed completely unaffected by it.
Since it deals with the Tractor system, putting it as a Science power seems logical, but it was also LtC Worf, a Tactical Officer, that came up with the idea, so putting it as a Tactical power would also make sense.
Constant exposure to the same opinions leads to continual reinforcement of ideas until eventually, any challenge, no matter what form it takes, is going to be met with a disproportionate sense of outrage. Room for reasoned discussion can no longer occur.
