This is just for the score whores but:
Right now, you'll get "obj assist" score for being close to the player capturing the obj.
Of course that doesn't really mean that you're actually helping your team in capturing the objectives, since the proper place to assist your team on objectives are usually far away from the objective itself. Say for example on silo, for the first and second obj you'll actually want to either be camping corp spawn and not near the terminal since anyone you can see when close to the terminal for the assist score are able to shoot or throw a nade at the decker.
Same goes for when you enable the terminal or sec override on undermine.
I'd suggest that you place out certain "zones" that gives assist score to players inside while obj is captured, or give score to people who were engaged: took/dealt a lot of damage right before the capture.
