Feel free to corect me ... But does not Bard, Paladin or Monk also do some "kind of" magic? O_o
I would say that this statement at best exclude Barbarian quite certainly (wich is odd imho, since i would expect them to come first ... they seem easiest to implement), but beyond that ... nothing.
Larian reversing their backstab/flanking advantage homebrew could be indicative of them working on the Barbarian and arriving at a very late epiphany that they were screwing Barbarians and their Reckless Attack over with it. On the other hand, it could also be that Larian simply realized their homebrew promoted shitty gameplay, but given their fondness for adding way too many highly questionable homebrew additions - the former is more likely.
It wasent homebrew. It was a literal interpretation of the rules. If you attack someone who cant see you (for example if you are behind them) you have advantage.
