Have battle high meter build for contributing in dealing damage to the pve enemys for both the Secure and Shatter front lines map. Like it just seems logical that the game would reward the player for actually doing the objectives of destroying ice/drones.

It obviously wouldn't make sense on Secure. As your already encouraged to do Attack/Defend with the various knowledge nodes.

And Danshig well, its like Secure so it wouldn't make sense, but its only attack/defend for getting to claim a point. Otherwise people just run off to some other objective as there isn't much point in sticking around like there is in Secure.
