One of the biggest complaints I or anyone else has about pickup groups is the lack of consistent skill in players. I propose to solve this by introducing a PvE fame system.
When participating with real humans in a mission, those humans would have the opportunity to annonymously raise or lower the fame of the other players by 1 when the mission ends. This fame would give you a displayable title (no suggestion on what the title is though). This title could be displayed, in order to indicate to other players your proficiency at PvE gaming, and thus make it easier to find good players for a party.
In addition, the easiest way to farm points for this title would be to help new players on early missions, which everyone appreciates, or to go on long mission-clearing streaks with your guildmates, which is also fun and skill-building.
Some might argue that this will introduce the same rank discrimination in PvE that we have in PvE. However, discriminating against bad players who ruin the fun of PuGs is not a crime, IMO.

always nice to meet another and XP doesn'r prove how skilled you are at playing a certian role.Skill comes from knowing how to play it not time spent.
