>>51803475Literally every example you listed was messed up because of JN, JN came *after* XY and is thus the fault of being inconsistent with what came before it. This isn't like a manga where XY diverged from Canon, JN fucked up by making Mega Lucario so strong or Alain and Diantha fodderized.
Also, good job showing you've never seen the show. Drasna never appeared in XY, so her performance in JN can't be inconsistent from XY.
