Lol, RNG abuse is definitely not cheating. Nintendo has said at VGC tournaments that it is the only legit way to get shiny/flawless Pokemon. It's like card counting, but it won't get you taken to the backroom and beaten.
X/Y won't be RNG'd until the 3DS and its encryption of the carts is cracked. When that happens, the RNG will be cracked as well.
