^^ As buttlover mentioned, it's very intuitive to 50/50 first and most of us who didn't would've immediately confirmed with a quick google search. Also, most don't make it as far as doing it to premium shrine units and can just reroll if they blow their KAtie, Iris, or Bashira etc. Just because a few dumbies didn't think about things doesn't mean they need to waste what little dev time our version already seems to get on stupid warnings.

If MWA does the former (letting you know you can CC at lvl 30) and neither tells you you should nor shouldn't do it, then that's not implying, that's just informing you of the option. It's certainly a nice option to have when we have skill changes after CC and need CC silvers for AW. Also, the game doesn't really even do this either, it really lets you figure out the game systems on your own. which is great considering they aren't incredibly difficult.

TLDR If you're spending money or large amounts of time on a game, I think it's intuitive to look up anything you have questions on before taking irreparable actions or blaming devs (this is one thing you can't blame them for).
