+spd - def fallen robin male

A +spd/-def Fallen Robin isn’t the best ivs but you could just give him defense +3.

We had a question about this exact IV earlier today. If you searched you would have found that I argue for him playing differently, using spd buffs to avoid doubles in order to compensate for having reduced bulk.

And I don't agree about that def+3 thing. There's a reason why def+3 is almost never recommended; it's a very inefficient use of a seal or A-skill slot. Would you use def+3 over close or distant def or even fortress def in any other situation? Why then does having 32 def mean he should do any differently? If anything, he wants to be even more efficient with his defenses. This idea people have about patching banes produces all kinds of ideas that they would dismiss as poor if they didn't know that there was a bane stat.

+res one is better
