while i do fly a BOP i also fly a sovy, i believe that the BOP, being more a fighter than anything else would be more prone to the acrobatic maneuvers than a large ship like a cruiser, simply put why would a cruiser do a barrel role, or a science ship for that matter.
i will admit i like mister dees idea best.
hmmm then you would be mistake. This is space. not earth or on a planet. anything can do a barrel roll. if you recall nemisis the sov a big ship did barrol rolls. The ability (" Not Power" cause this isnt wow) should be able to fire at any arc. This ability allows for diverse shield attack, allowing your ships shield parts to take equal fire
the ability can last 6 seconds and the cool down is 45 seconds. It can be mainly a defensive ability for admirals. yes thats right i said admiral. fleet admiral will be a can of worms i dont think cryptic wants to open ever. main because you only really have 1 fleet admiral and well hmm when has star trek shown a fleet admiral.
I feel compelled to point out that no one in this thread seems to know what a barrel roll actually is. Barrel rolls are already possible in STO, although they don't work the way you imagine, and don't need to function the way they do in aircraft since aircraft need to generate lift, but they are still useful in STO for the most of the same reasons they are useful in aircraft maneuvering.
The barrel roll is so named because an aircraft executing this maneuver looks as though it were flying with its wheels running along the inside edge of a barrel. A more common modern visualization is to imagine an airplane trying to fly in a horizontal corkscrew around the line of the direction of travel.
Everyone seems to be thinking of an aileron roll instead that has no actual maneuver value.
But if you want to do an actual barrel roll, you already can. Its good for "slowing down" without actually slowing down. If you think of it like a corkscrew, the length from one end to the other of the corkscrew is much shorter than if you were to completely straighten out the corkscrew.
So if there are two ships, one traveling the length of the corkscrew, the other traveling the path of the corkscrew, both start at the same point, and move at the same speed, the one traveling the corkscrew path will end up behind the other ship, despite never touching the throttle. That is what a barrel roll does and how it can be useful. It does work in STO, and you don't need to roll the ship to do it.
