Sorry I'm some what confused by this. If I want to hunt a Snorlax on route 11, I have to faint a level 20 pokemon and have it as the lead for the repel to work and only show me Snorlax? And I only need Sync on my 2nd pokemon if I want the Snorlax I'm looking for to have a 50% chance of having the same Nature? So is the Sync pokemon even required if I just wanna get Snorlax regardless of it's nature?

If they were to add guild perks, that's just forcing people who don't want to join a guild to join one. So sorry, but it's a horrible idea.
