I already have flawless legendaries EVed appropriately at level 100. I don't want to advance because I might release new roaming legendaries. If I'm wrong, I'd be glad to finish the game so I can open up Battle Frontier and have access to new catch/hatch locations.
That's unfortunate because I haven't even beat the elite 4 yet in Platinum and I barely have 3 KANTO badges in SS. RNGing for flawless IVs takes a long time; I'm not sure if I'll be up for it later on: I'm burnt out and school starts next Monday. Maybe during winter break lol.
