Why should you download it?

Unlike typical heavy optimization plugins that ruin the vanilla experience-such as completely breaking item farms, limiting useful mechanics like rocket fireworks, or artificially capping mob behaviors-LagSentinel focuses purely on precision and safety. It doesn't interfere with your gameplay or restrict fun mechanics during normal play; it only steps in as an intelligent safety net during actual server emergencies, freezing only the specific overloaded chunks and purging only excessive lag spam while keeping your legitimate builds, items, and farms completely intact.
