Basic Competence

Killing enemy players is by far and away the easiest way to push the crystal, so the argument of whether killing players or pushing the crystal is more important makes no sense to begin with. The former precedes the latter 90% of the time.

The actual argument underneath is whether you should move off the crystal to finish off low runners before they can pot, or let them go to stand on the crystal, which has an obvious most-of-the-time correct answer. Go finish off the runner, secure the kill, and get a numbers advantage, which makes the enemy team back off the crystal. Then you can actually move the objective because the enemy team isn’t cockblocking you by planting themselves on the objective as well. Because you’ve forced them to move off the crystal. By killing enough of them to make them regroup or trickle.

You can stand on the crystal for the next hundred years and not move it an inch if you don’t kill the enemy team so they’re not standing on it with you. Following through to secure the kill as much as possible (without overextending and dying) when enemy players are low is really REALLY REALLY important.
