So yeh. Nearly 150000 XP to reach level 50. Keep in mind, mining one ore gives you 15 XP. You guys are sure in for a treat ;D
Try to understand that this is a Blockland server, and not an MMORPG game. Player's won't spend nearly as much time on the server as they would a professional game, and as such I believe the experience requirements should be much,
much lower than you currently have them set.
Grinding and such isn't the point when playing a server. The point of grinding in larger games is to keep the playerbase playing for that much needed in-game time... so they last longer, spending more money. You aren't (I hope) profiting off of this, I'd assume.
Just a suggestion.
