This is why i hate the unnecessary perfectionist trend here on Gamefaqs. Dude, your defense is only around 8 points lower than max, if not, then only by 5 points. It's such a small factor, it doesn't actually matter for a Pokemon like Greninja (he's going to be frail regardless). Of course that Froakie is viable competitively, and you're only doubting it's not because of the weird OCD that Gamefaqs has. I reckon use it and move on to the next Pokemon you desire to be bred for competitive play.
Good enough depends on how competitive you want to be. Ideally, you wouldn't settle for less than perfect.
Greninja has utterly crap defensive stats anyways; I doubt the extra 5-8 defense is going to help him any. He has perfect Atk, Sp. Atk, and Speed IVs, and for a sweeper, isn't that about all you REALLY need, unless they're bulky enough to take a hit or two?
Thank you both! :)
