We need a cross between the old system (basically what deej says below is "number of posts without being banned". And I'm being extremely simple in that quote.) and a new one. It is important to be active in the community to put up posts and participate but as we all know some of those posts are inane gibberish. But it's still important to note who's active. I wish I had a fresh take on a new system but don't take away the old one either. Some in game context would be great. Imagine if bungie put out some custom challenges that highlighted being a good community member. Stuff like "helping a person who's never done this quest before" or "saving a fellow guardian from peril". I think your take is only looking at competitive play in which case you are right. But don't forget about cooperative. If you remember back to the vid master challenges there were great community members who helped tons of people get many of those achievements for recon. There's definitely a way to tie in both.
