For the most part, I deal with teleporters with really awkward, jerky movement that idk how to explain. I can say that I think when I don't have to get data, I mostly just click up-right-down-up repeating, not completely sure that's what I do because I do it rather fast but it works for the most part, either way want lots of shield and imperfect speed.
Killing them, I feel like the main reason my opinion on orbitals has gone up is because I feel like they're good specifically for them, although I could be mistaken, it's impossible to tell frankly. I'm personally not too bothered by bullets in general(because mostly they don't feel like they deal much damage and aren't hard to dodge unless there's a lot(typically a damage problem), which is admittedly a bad attitude), but just 2 flak feels like enough to deal with most all bullets anyways.
