I guess I'll start from the beginning since it seems like people are confused.
I just want the two remaining random roles to claim today. When they claim doesn't matter, just as long as it happens today. Why today? Because we need to make a decision on lynching today. It narrows the eventual claim space for the evils when they get pressed.
If you are a villager, there is no legitimate reason to want to keep a random role hidden. The chances that we would be helping the Dingo are small, but the value to the village in claiming is tremendous. Villagers should want to help the village win. If you are afraid of claiming because you want to prioritize your own long-term survival over helping the village win, you frankly aren't a good teammate.
If you are a predator, you should be pushing very hard against claiming. Having to make a claim puts you in a box from which you cannot hide.
When TD says "We just lynch the last to claim", that is true, in that if 4 people claim the random roles and then someone else tries to claim one later on Day 5, they're gonna die. That's just logic. Not because "they claimed last", but because they allowed someone else to claim their role for days and said absolutely nothing about it.
