Level minimum and maximum XP (levels)
This is not an issue and leans more to a person's opinion. I'd like to know how much extra XP would be required every level up since it took so less messages to reach level 1. I'm deciding on what to set the XP per minute be, but I'm not sure what would be easy and what not.
Solution
Since I don't know your servers setup I can't give you a personal recommendation, but I can direct you to our Level Calculator that tells you how much XP someone needs to reach a certain Level and also roughly how long it would take. https://lurkr.gg/levels/calculator
