As of right now, most objectives give between a range of 25 to 50 points on average, while kills are 100 each. Killing objective holders adds 25 XP to the 100 kill XP. The only exception are flag captures, which give out 300 points.
If score is taken into account for Battle Pass progression, people will not have an incentive to play as a team. They’ll play as selfishly as before, going for kills rather than objectives.
