I kind of know what they mean, but I have no idea why they decided to do it this way and the system just seems so annoying that I'd rather not work with it. I hear stories of "oh, I had to hatch like 50 eggs because none of them had the IVs I wanted" and I'm like... "wheeee, so glad I don't care about competitive battling!" And then you have the whole OU, UU, and whatever tiers people try to build teams for and that's yet another thing that eludes me. Hence, this is why I've never bred a Pokemon with perfect IVs and then EV trained it. Chances are good if I even tried it, I would flunk on something stupid like giving it the wrong moves, giving it the wrong held item, or something like that even after all that research and effort. Bleh.

Call it ADHD, but I'd rather just have more fun with the characters themselves in terms of drawing them, making RPs with them, and so on rather than try to math everything. So yeah, I'll probably never be a real competitive battler, but I hope those who decide to do that kind of thing have fun with it. It's just not my cup of tea.
