Don't JUST be a slayer, be a player too.

There's a chance that someone ISN'T always following you... So, when you kill someone, pick up their core file. Then, bolt to the deposit zone. Also, when your team dies, if you think you can kill the guy that picks up the core files, let them pick it up. If you aren't that good at the game, then go and deny those sons of biches. Slayers, of course, will normally be very good at the game, so the last part of that sentence was just extra help...
