EV Training is super easy and quick. Although learning and understanding about it took a while. IV training took a week for me to figure out including everstone trick, slugma, and calculator/etc. Plus IV breeding takes days for perf IVs. So people stop showing off your EVed pokemon because a Perf IVed/EVed pokemon will own a EVed pokemon. Plus EV training fairly takes not too much effort if you have PKRS, Power items and Vitamins not really so pro but the effects of EV training is great but adding the IV breeding makes it x4 greater!
