Adding a newton launcher would be so much fun honestly, you could pop people up for some skeet shootingFor those reasons I think some ways to make it more interesting it would be cool maybe if players spawned in with Newton Launchers as well, which allows them to knock players in the air. I think it could create some funny moments. Personally I would also love if this allowed everyone to use the Newton Launcher boosting ability that is purchasable from the pointshop, so you have way cooler movement options rather than just "jump and be forced to float slowly".
Part of the meta of the round to me though is also resisting the urge to fortnite jump around while shooting like a lot of people do, so you have to duck and weave instead. But NLs would be super chaotic and that's a better option to me than getting rid of the round, though it seems most people like it by the votesthe slow gravity makes you a super easy target if you even dare to jump, especially if you end up in one of those awkward situations where you are just floating down slowly.
