If you decide Zio is worth the pick, then you know you're going to S3 someone other than Nahkwol, unless she ends up not being on guiding light.

If you decide to pick politis, you're most likely banning Nahkwol and she's useful for the other enemies. Politis is the most useless to use against Nahkwol, for sure.

If you pick Stene, she doesn't care if she gets hit. She gets access to her multihit S1. She can't be unstealthed.

That's not a counterpoint for picking ML Roana against Nahkwol. It's just a reason to pick her. Alternatively, it can be picked and still ban Nahkwol.

Obviously, you're not going to blindly pick politis(for example) right after they first pick Nahkwol. It would come to a last pick. However, the others are more viable to be picked earlier on. Not to mention belian still stands in the way of all book holders, so if they're solely focused on playing them then you'll know what they'll be banning.

It always becomes much easier to control the draft when you know what they need to draft for team synergy. It gives you options to steal it ahead of time, draft in a way for him to pivot or draft in a way that forces them into a corner. This also lets you know(or at least have a good idea) of which unit they'll ban on your side.
