Would EV training be easier in HG/SS?

Question

Why? because of the gym leaders most of them have a type for example brok has a bunch of rock types which often are the ones giving defense EVs, etc

Answer 1

This seems like more effort to me. Yes, Rock types often give off Defence, but not always. Eg Kabutops gives off 2 Attack (im pretty sure Brock has one of those) and other types don't really have any EV association with them. What about Whitney's Normal types? So this is not something I would try. Keep your competitive and in-game teams seperate.
