If a lobby was good/fun enough I don't think xp would really matter to the majority of players.
Limited xp was meant to stop boosting which is perfectly well and good for a game at launch but we're at the point now they may as well open the floodgates so people can really test attachments.
The problem with wacky settings is the ammount of stress it puts on the lobby though - In my experience, the more you start tweaking the experience, the laggier it gets
i will take that in count when tinkering on portal
and yeah for me its not like i need that xp, i just think about the new players
