I've had this said to me before in a few battles at school the kid is using an all legends team and im using my rag tag team used in game.
He says legends can't be beat i proceed to sweep his entire team with my Lucario he goes on and says i cheated becaus ei beat his legend i told him how i trained and he said that is cheating and i told him no its in game and such still Says cheating has something like this happen to any of you if so what have you said thought or felt about it?
They way I see it, there is no way to avoid EV-training unless you started to feed your pokemon rare candies from the moment you caught/hatched it or paid several visits to the Dojo in B/W2. The thing is that everyone is EV-training whether they do it consciously or not. You're pokemon will gain EV's from battles and those will go to their respective stats. Yet, those who choose not to properly EV-train their pokemon are putting themselves at an unnecessary disadvantage to keep their morals high even though GameFreak has subtly shown ingame that they acknowledge the existence of EV's and give players the freedom to manipulate them as they wish. So again, saying EV-training is cheating is a ridiculous and ignorant thing to say and you're only hurting yourself with such statements.
Those are my two cents, don't spend it all at once.
