While I agree that skills are more important than gear, that some requirements are way overkill for the content, and that I also find that the more important pieces like body and legs should be worth more in the average balance of the ilvl, I don't see why anyone would want to have less freedom to chose who they want in their party.
If the party leaders who set those high requirements can't find people in reasonable time, they will lower the requirements, the market law appplies there too. If they find people, we can't really complain, they make parties for their needs, not ours. And if he's here to get carried, leave his party.
