Pokemon is an RPG, there is going to be a grind. Not to mention PRO is an MMO, making it an MMORPG like World of Warcraft. And like World of Warcraft, there is going to be a huge grind to get the best stuff. That's why to me it doesn't make sense to change the system at all, because PRO is an MMORPG that's just as grindy as the rest. Not to mention changing EV training would be straying from the games quite a bit.
I get where you are coming from, just my 2 cents.
