Convincing people starting FFXIV to keep playing:
Broke: "Heavensward and Shadowbringers are better than a lot of mainline FFs"
Woke: "bro, everyone in Shadowbringers gets REALLY HOT"
Time Mage could also work
Not sure if it's possible with XIV's engine, but it would be fun to see their restoration spell not actually heal but instead rewind your HP to a previous point in time, though I'm sure that would be kinda chaotic in big groups
