Not everyone cares for pokemon enough to learn those concepts. Pokemon has become so awfully predictable with the introduction of mass competitive play (wifi, in other words) and time consuming, with all these EV's, IV's, STANDARD MOVESETS, TIERS, it's all planned out, there's no originality. It's only how you use them combined with a little bit of luck. And since sites like Smogon have come out they put their full weight behind competitive battling, so any trainer that wants a simple battle can scarcely find one without battling an EV/IV training expert. Standard rules make things too...well, STANDARD. That's boring, and it's all the same stuff, the more clauses and rules you tack onto it.
