I can understand that ppl think BSF was released too soon after Revan, I don’t have Revan but when he was released I felt that it was too soon after I had finally managed to farm Traya and Sion.
However, while Revan was meta shifting BSF is not, she is at best a possible counter on offense (and even that is far from a sure win) but get smashed on def (just as jedi Bastilla was a counter to the zPalp/zader meta and not a true meta in itself).
Revan is still the unchallenged meta, yes other teams can beat him but none other currently hold as well on defence.
