After some deliberation on this issue, I'm going to have to go with Group B. I originally supported your decision to 'put your foot down', because I feel that there is a reason that we have a leader for this whole process and that the leader should be vocal enough to decide on certain issues. Even though I strongly disagreed with your take on the philosophy of following in-game mechanics, I was willing to accept this decision on the basis of moving forward with Gen V.
However, I have come to believe that this decision was wrong. Although I believe that the chief executive in the Gen V deciding process should reserve the right to make such decisions, I am not comfortable with a leader overturning a supermajority such as the one we had because of his own deeply-rooted ideological views. I feel that there should have been more behind the decision, be it majority's support or more sound logical conviction. As I mentioned before, I am strongly against those who say that modifying the cartridge mechanics in any ways will constitute a shift away from Pokemon into "Smogonmon", as the game is still the game if we make such a miniscule shift that does not change the fundamentals at all. With that said, your justification for ruling the way you did was nothing but a poorly supported (by the PR forum, not the reasoning) dissenting opinion. It's equivalent to the US President bringing a controversial law to Congress, seeing that a supermajority wants to pass it, and then being able to veto anyway. I'd like to think that there is a reason for this forum, and that we participants have a say in the issues that cannot be brushed aside like this.
Again, I support a powerful leader as Gen V develops, but certainly not on cases like this where we have a clear consensus in one direction on an issue that is not as complex as it is being made out by some people to be. I generally would support an action like this, but this situation seems unacceptable to me and I agree wholeheartedly with Group B.
