I propose a primary AR with a different type of explosive rounds. You would have a toggle (similar to the Murmur) where you can select "Standard Rounds" or "Magnetic Explosive Rounds". The rounds do not track, but each round that hits the target, sticks to the target. They wouldn't actually do any damage until detonated. When the desired number of rounds are reached, a trigger can detonate the rounds, doing various levels of damage depending on how many rounds have hit the mark. If the "sender" dies before detonating, the rounds simply disappear, just like a Titan's bubble once they die... The risk vs rewards factor comes into play... Do I take him out now (Standard Rounds), or risk getting wiped before having the chance to detonate? Do I get the hits in, and wait, enjoying the panic that player must be feeling while they wait to meet their demise? Am I too cocky, and get killed by that player while I'm waiting? These are just a few scenarios. I'm unsure if this weapon should have any kind of elemental effect or not though. Just something that came to me...
