If they keep a few new players from getting frustrated due to the games learning curve, their benefits outweigh the drawbacks or their ability to pull moves that a real pilot would/could never pull off.
Concerning the Brew, I'm no aircraft expert but when I came back to the game a few months ago it took a while to realize that the Brew on my tail wasn't a 2nd one I didn't see. It was the same one that did a flat 180 turn behind me but I wrote off because I'm cruising along straight at a good speed and there's no way he could complete that turn, that tight, and be shooting at me.
No idea if their ability to swap ends with minimal E bleed is accurate, but it certainly is a surprise for a lot of folks use to flying against the rest of the plane set. Once known its just something you plan accordingly for.
