Have you transferred all of your bros from past gens, or are you going to?

While I brought over my team from Platinum, who would otherwise simply have rotted in a game I won't ever finish anyway, I'm hesitant about the rest of them. Within their games, they are special; and whenever I would go back to them, my bros would be waiting for me and get used; but in Y? They would probably just sit in the PC, overshadowed by recent 5–6IV masterrace breeds.
Keeping them decentralised also minimises the risk of losing them all.

On the other hand, being stuck in the past in rarely-used old games is not a kind fate either, and importing any important Pokémon would allow me to re-play some earlier titles without losing anything.
