Suggestion: "Team Player" Rating

Team - 

This game is truly a blast and I look forward to future updates.

As I've been playing over the last few weeks, it's been great to experience being on teams with players who although being complete strangers, will go out of their way to provide support to their fellow teammates i.e. by pinging enemies or supplies, or will even run back into the storm to revive a fallen comrade.  On the unfortunate other end are players who simply loot the carcasses of their teammates take it upon themselves begin a solo campaign, leaving the fallen to either spectate or leave the game altogether to start a new one.  While some may perceive this as merely par for the course of online gaming, it actually becomes immensely frustrating when you or the fallen comrades has contributed to more than half of the kills thus far in the campaign.

I suggest creating a rating system by which teammates can rate the "Team Player" willingness of each of their teammates following each game, much like a yelp review.  No comments or bad-mouthing, but merely a 1 - 5 rating or perhaps a Red, Yellow, Green rating.  This becomes a team-play promoting stat for players to work toward.  When beginning each game we often see the total number of kills someone has, or the total number of scans, etc.  But we often don't know what were getting into with our fellow teammates until it's too late and there exists little incentive for these lone wolf scrotes to adapt to the heart of the game, which is... team play.
