>>21117526That won't really get you anything useful, outside 6IV Dittos. Injecting into genVI is a pain in the ass and requires a JP cart and a cybergadget editor (Japanese Powersave that can inject Pokémon and only works on JP carts).
SRing for decent Zapdoses isn't that difficult in XY with guaranteed 3IVs - a few dozen hours of SRing should net you a pretty decent one with a hidden power. Given how much of a pain in the ass injection is (and PowerSaves not being usable for hacking IVs at the time), most of the Zapdoses at Worlds were probably legit SRs. It's possible everyone was using a clone of some injected shit from Japan, of course, but that seems unlikely.
For VGC2015, I definitely agree that PowerSave will be the order of the day if GF continues to ban Bank Pokémon from VGC. Especially for Latios/Latias, which may possibly be extremely painful to SR in ORAS, depending on how it works out.
