Therefore, Pokecheck is the best thing ever for me, but too bad there isn't an EV trained petilil that I can find.
I generally do this last part for myself now, too - especially in the gen 5 era because I'm competent with abusing the RNG. Usually, I lay off the fully EV trained part, though, because you really crush the game when all you're doing is level grinding a competitively bred and trained monster... It gets very, very boring one shot-ing everything... perfect IVs and favorable nature is already more than enough. But yeah, I'm OCD ever since traveling through the wormhole...
To respond more to the original post:
No, I don't regret knowing the ins and outs of Pokemon. I started playing this game when Blue version was all the rage and gameboys/trading cards were getting banned from middle school. In a way, I've evolved along with the game. The progression from gen 1 to gen 5 mirrors my own involvement and awareness. RBY is very simple compared to today's game. Likewise, I was blissfully unaware that a competitive community existed. Gen 2 introduced a lot of changes that laid the groundwork for future generations. I first learned the competitive ins and outs during GSC and it set up my increased interest in person vs person battling in gen 3. And so on... you get the idea.
To me, that was the natural progression. You either get more obsessed, more involved or you casually play the game and then drop off. With GBU and wifi battles as an option, it's tough to really argue there's a happy middle ground if you're competitive like me and always have to win. I wouldn't undo it because that's just how it goes.
For a new game, the way I always play it is what we're calling "pure" - though, as mentioned above, I will manipulate the RNG and/or hunt down beneficial IVs/natures.
I imported the Japanese version of White 2 at release so I can tell you my opinion of how to go about it: play it out of the box. It's arguably the best in-game Pokemon experience of them all with the features and available team options along the way. It's enjoyable enough that worrying about perfect competitive pokemon would ruin it a bit, IMO.
Also, I wouldn't want to trade over something like Gible or Larvitar to start a game... slow growth rate, yuck!
