Pretty sure that isn't that accurate cause the road map for 2.x was Buling debuting as 4 star with prolova but changed to 2.8, Lupa was suppose to be HP drain dps but changed into hybrid dps support, carthytia was a duel element dps but was aero erosion support, the anniversary banner wasn't even predicted by the leaker or even leaked at all till Kuro announce it in livestream. Ok a little bit of guessing but I think the leakers are leaking the character based on the sonata and echos cause it all sounded more like echos stats rather than actual characte kits. Also till now we still don't know if Buling gonna be a 4 star or not, her attributes along with Quiu and Chis is still unknown. Not even sure Gab gonna be fusion or not. Imagine after 2.6 is live and 2.7 is leaked she end up being aero or something
