Imo it's just shitty for the people not able to 24/7 the game or got unlucky so far so they pretty much missed out on Tini and Larv. Especially since Larv is blocked behind OT Dex. Sure I am bias right now being at 60k encounters in total split across both spots and not getting anything but in general I find it unfair since it seems to be a heavy hit, not just "lets make 50:50 into 40:60 or 1/3 : 2/3.
Edit: Also a heads up on such changes would be nice, making people able to priorities certain hordes if they have multiple spots they are hunting at least until such changes hit live.
