I've read a few people complain about the currently limited scope for achievement in Multiplayer Mode. Your performance in each battle being based purely on your kill/death ratio isn't a particularly effective way of gauging just how good a given player is, especially considering the essential importance of assists and healing when looking to achieve victory, so I've come up with a system which would ensure that all players recieve recognition for their contributions during a match.

Your 'Skillstreak' is represented by a bar in the bottom left corner of the screen, conveniently broken up into 7 sections. Each section is the equivalent of 4.5 energy bars (the average energy between all classes), and you fill each section by either taking that amount of energy from the opposing team, or restoring it to your own. This means that you don't need to actually KILL your enemies to start getting Skillstreak bonuses (though that would be a the fastest way), if you wish you can simply stay at arms length and steadily scrape energy off them to build your meter, or do so by playing medic and keeping your team mates alive. The meter resets should you be killed, and although it only has 7 sections additional meter built beyond this will still show up in your stats, and at the end of the match rather than just listing each players kill/death ratio, the amount of total damage each player dealt/recieved/restored will also be displayed, and is used to allocate one player the 'MVP' reward (who doesn't even have to be on the winning team).

 

They could set it up like modern warfare 3 where things like kills, assists, revives all give you points, when you get enough points you get the ability.
