Did some RNG's yesterday (will post them to the Discuss my Poke thread later) and read up on Dream Radar RNGing
Turns out there's no trial and error for Dream Radar RNGing. So if you fail to hit your seed or fail to hit your frame, you can't reset and try again. Which sounds like a pain in the ***.
So is it worth RNGing the legends that come out of the Dream Radar?
