In case you haven't noticed, they haven't done any arcs that had more than 4 eps since BW. And I don't think you understand what development actually is or what's even rushed in the first place.Galarian farfetch'd is the coolest pokemon ash caught this season and it isn't even getting 5 min of screentime. His presence is even less than some of gou's mons. And this arc also seems to be a bit rushed. Eevee was 100% right about this arc. This arc deserved at least 6 episode for more character interaction and development. Instead both riolu and raboot are gonna evolve with no real development at all whatsoever. Wild eternatus appears and these two mons just go super saiyan.
