Looks like I found the thread I was looking for.
I don't like the new PP system, but at the same time I believe the decision to have one was a good choice. This game has 22k+ ranked maps, and this makes it very difficult for new players to rank up.
In the old system, ranking up doesn't imply skill, but rather time. However, time=experience=skill; so to an extent having a high rank would generally mean you're good at the game.
This new system is kind of similar because it's point based, but to gain points you need to rank on the top 500's. The amount of points you gain is based on how 'difficult' the map is. This new system kind of implies you already have experience, and it rewards you for doing good on individual maps.
What I don't like about the new system is that you have to rank in the top 500's to get PP. This endorses the player to play the same map over and over again until they get a good score. I don't like that type of game play, and this is the whole point of my post.
Overall I'm fine with having PP shown in my stats but having my picture-tag-thing in game show my PP rank instead of the other system I do not like. The new system shows us skill, but experience is a very important achievement too. I think of the old system as kind of a single player game achievement sort of thing: do maps, accumulate points, get higher in ranks. It's nice. The new system forces you to be less casual.
I'd like to see my picture-tag-thing in game to show the older system again, and have PP stats shown on your main page.
Oh, and I don't like how old maps (and new ones that age) will not be considered in the PP system.
Summary: I don't like how the system promotes hardcore players and alienates the less serious but skilled peeps.
