Scorestreaks, especially for OBJ game types, it makes those people who might not be super good in TDM feel like they can still contribute. In DOM iv seen guys with .5kdr end up in the top 3 for points because they played the OBJ and their scorestreaks helped out in the long run.
How on earth will someone like killstreak? This thing makes objective games stupid because You can ignore them and only go for kills while scorestreak gives you something for going for the objective. People voting killstreak are those that never go for objective and only care about kills.
