Or…just wait until the champ’s info is in the champion pool in a couple days and just click and see what they are for yourself. I don’t see how not mentioning synergies in the deep dive affects literally anything before the champ’s info is in-game.
To be honest, Ranking someone purely for Synergies isn't a good practice. Of course people can do it if they want, but if the only purpose a Champ has on my team is for that, I'm using up a space, and they don't need Ranked just for the Synergy.
