Guess what, people can go out start their own business/company in real life too. Be your own boss, but that works how well again?
Telling new players they are NOT wanted, is a no go for SE. The top 1% don't need more tools to exclude other players. Not to mention this clearance condition will be a boon for clear sellers and RMT.
Nope not exaggerating. How many people to this day still need to clear T5 or Titan EX. Go poll the people online in game. You get lucky to find more than 5% of them to have cleared both, that number is probably closer to 1%. And T9, there are not that many statics that can do that at all. It is same group of people that can afford the houses now being priced so that only the top 1% have the gil on hand to acquire those. Same reason why T5/Titan EX clears are being sold at 1mil per run.
Nobody is dictating to them. Remember these are the people that dictate to the unwashed masses of newer players to stay away from them on the PF. They don't need tools in the system to make that even easier. They can kick and they do kick, but at least they have to try. And who are you to tell people to be quiet. It is not about moral values anyways, it is about enlightened self-interest. By getting more access to more people, it helps SE, and helps the player base, and in turn helps myself to have more people to play with, and more chances to clear new challenging content. It is taking the long view and bigger picture approach. There will only be fewer and fewer people to draw from the further up the ladder, and that "clear condition" will basically exclude everyone before you know it.
Imagine on day one of SCOB being released, it will be a real laugh to see people setting the clearance condition flag for cleared T9, most likely because they haven't even cleared T6 themselves, and then complain about how they can't find anyone as good as themselves.
