1. Is there an easier way to get to the end than instructed in minecraft wiki? For example there is a /warp nether in the game. Is there one for the end?

2. Why do people use vaults. If someone has their chests locked, how does that make it different from vaults?

/warp end is the warp to the end. People use vaults because no matter what security features the server uses, it's always safer to have them stored in a safer place. Just in case the plugin were to crash.

I tried using /warp end before but it didn't work. Im guessing it was due to lag or something. Thanks. Helps a lot
