It's a good idea, But it'll take a very long time to develop it and make it synced with servers; not saying CubedCraft development team cannot do this, but they will need to make it synced and correct for every once of their gamemodes; it's pretty bad just having it for only one gamemode - and players will want all the gamemodes on the website leaderboard. I do have to agree with a few others though, it would sort of stop the challenge of people wanting to try and get to the top 3 in-game located on various gamemodes lobbies. This is just my opinion though, but an online one would be nice to see who's catching up to you, or if you're doing better than your friends. Overall, I'm kind of unsure of whether it's necessary or not.
