This may be the best idea that's been said. For the simple reason that it's not us making up rules. Playing strict DP is playing one version of "pokemon as it is given to us". That said, everything still gets Draco Meteor in DP. It's only Outrage that isn't widespread.
Pokemon wasn't given to us. It was given to the much wider audience, who have no concept of "competitive" or "metagame". This much is very clear, and understandable since the makers are only after money.
If they were ever going to cater for this side of Pokemon, they certainly won't anymore because of Shoddy. The most obvious fact about competitive Pokemon is that it's centred around Shoddy, it all happens in Shoddy. For competitive minded people, there's no point buying the cartridge.
X-Act, you say GameFreak made a mistake when they introduced Outrage. No, it wasn't a mistake, because they don't give a flying fuck about competitive Pokemon, if they even know anything about it. I agree that Outrage has had some bad effects on us, but that means nothing to them.
People are very adamant about playing the game "as it is". But if you insist on this, you can't complain about an imbalanced metagame. The game was not designed to have a balanced metagame and anything not designed for balance will be very imbalanced without some incredible luck. So, by playing the game as is, you're choosing to deal with something you'll never even get close to balanced. The lengths you've gone to achieve it are admirable, not complaining there, but in the end you unfortunately can't win because the pure base of what you're working with is too flawed in the first place.
So, there are two possible reasons why everyone insists on keeping with competitive Pokemon "as it is".
1. They don't realise the above fact, or choose to ignore it
OR the much more likely
2. It's the only true middleground; any attempt to alter the game will result in endless arguments and wars over what happens. "Who will ultimately decide?" would be the unanswerable question.
So in the end we choose the invisible presence, the one not involved in any discussion, the one with no concept of what we're on about: GameFreak. Leave the game as is, we say. Leave it to GameFreak to set the foundation.
Basically, we're all GameFreak's bitch. We've appointed them universal lords of something they don't give a shit about: Competitive Pokemon.
Btw I'm not trying to achieve anything here. Not suggesting it's a bad idea sticking with the game as it is. Not suggesting we go in a different direction. Just voicing my thoughts on the problem at hand. It's an endless pit really, no definable solution.
Now, on the topic of strict DP as an option. I also like that idea. I enjoyed the game a lot more during DP days and played a lot; in fact, it wasn't so long after Platinum was released that I lost interest. So Platinum could very likely be the reason.
