I guess in pvp Scramble Sensors might not be as useful, but in say defend sector missions it was really fun to use. You know those big blobs of ships and everyone's hesitant to be the first to engage, well I just flew right in and fired off Scramble Sensors and all the NPCs started shooting at each other
It was really funny, and I could actually take out a blob on my own with relative ease as I had cut down 2.5 of the bigger ships before the got their focused fire back on me again. Of course using a variety of other skills as well, like Reverse Shield Polarity and so on.
But, I wonder, do other people use this skill? I really liked it for pve, at least.
I use the II version all the time in pvp, I get a good 29 seconds off of it. Since I'm an Engineer in a science vessel, I don't have the luxury of rank III, but if you see the enemy just firing away, it's great to just shoot it off and watch them start shooting each other. I've made a fair number of kills off Klingon BoPs just from them shooting their own.
In Deep Space Encounters with the Borg, it's pretty cool too. The cubes mostly take up most of the AOE effect if you target them, but just watching them disable the shields of the surrounding spheres and probes is priceless. If you target a probe or a sphere, you can sometimes get a cube. My tactics are usually involve a full impulse death-charge in, find one in the "middle" of the pack, pop scramble, and then everything to shields...and pray I survive long enough for them to start targetting something that's not me...
