Honestly AST had great potential with the 2 sects but they just went the easy route and scrapped it for their ridiculous pure/barrier split...

Imagine being able to swap diurnal/nocturnal mid battle with something like Celestial Opposition for example on a 60s cd which would also change your new draw aspect cards would be quite fun to plan ahead and change things up a bit

Although I think I'd still preferred some old card buttons to come back like the card spread or time dilation
