Loot Tickets are a Joke - They completely miss the point

I’m guessing loot tickets require world energy as a way to limit how fast and freely harder map levels can be auto-farmed

Yes, but you appear to be looking at it from a game balance perspective.

F2P MMOs require energy meters because there is no such thing as a free lunch. Because of energy meters, loot tickets still need energy:

==Loot tickets==
Loot tickets cost energy because of how the load on the server ( which costs real money) works for F2P MMOs (see HOT lane example ). Loot tickets can be bought for real money for the same reasons as energy refills ( see above recouping server costs ). Yes, this means you are paying twice, but as the HOT lane example above shows, that further reduces load by make a player think THREE times before using a loot ticket which substantially spikes server loads, server storage needed and increases server code maintenance costs.
