When I tried to play competitive, I spent a good month breeding for perfect IVs in at least 3 stats (the ones I was looking for)
-I did not like, though, when the BW judge called its spread "decent" though
But, this conversation about using PokeGen, I'm kinda convinced on using it, but only for these reasons:
-Getting Pokemon like Mew, Celebi, Jirachi, Deoxys, Shaymin, Arceus, and Manaphy (since I couldn't obtain them previously)
-Boosting the IV spread higher (like 31s in the favorable stats, 20s or so in the others)
I would still EV train and breed for Natures and such (since I really enjoy doing that) but I'd only use to complete the Pokedex/boost my WiFi competitive team.
Does that make me a bad person?
Also, is there any downsides that anyone has encountered when "hacking" Legendaries to games for Pokedex purposes?
