Nobody can one-shot except gunships with a particular companion skill.
Also if it makes you dizzy that doesn't mean it isn't a fuild flight game that just means your brain is having issues with the speed and manuevring.
Also, the cartel ships are identical to existing ships they have ZERO advantages over standard ships.
No difference is, is that i if you don't buy the equivalent ships from the Cartel you have to play to unlock them. Buying from the Cartel means skipping ships and having access to higher / better ships without the grind, aka Pay to Win.
