I know personally that we have things like the Money and Mcmmo multipliers we can win in crates, But what if there was something more to this? Maybe having things like "Mcmmo Bomb" "XP Bomb" "Money Bomb" that we could buy in the webstore! I feel like a fair price could be 4 bombs for 5$ and extend that to however many more there would be. I feel like a duration of 20 minutes is more than fair per bomb, But here's the catch! They're server-wide once active, meaning that everyone on server would be able to enjoy the boosts.
