New Darkin Ideas

Anyone else thinking about what the next darkin(s) will be? I'm thinking it will be a mid laner and a sup because there are supposed to be 5, but i think recently I was told one wasnt coming back and there were now 4, my lore knowledge isnt the best if anyone knows anything about that plz correct me. But I was thinking it'd be a mid laner because we have a top lane(Aatrox), jg ( Kayn/Rhaast), and an adc (varus). I was thinking theyd make a darkin mid laner/ support. I just hope they dont make morgana and kayle darkin/ ascended because reasons and actually make 2 new characters. On that note, how do you think they'd play? I like aatrox and rhaast because they play like they're meant to be, kind of slow but powerful. I dont really like varus in that sense because hes strictly attack speed, but i guess hes still half human.
