The aim was for these challenges to be finished within the first month at most so that all the RW are revealed while everyone is still playing and you have something new to experiment and build with. That's why it's a community challenge, no one is asking you to solo all the stuff.
The challenge for veterans is not "can you do this?", but rather "can you be first?".
And yes to people who didn't understand the OP too well - whenever a challenge is completed the RW "recipe" will be posted here for everyone to see and also announced on TSW together with the people who unlocked it.
