there is virtually no difference between noble and royal, god gets a little bit cooler stuff doe but its not worth spending 20 (15 USD now) on basically a different colored name and prefix
Here is a better idea: 1 on Free, 2 on Noble, 3 on Royal, 4 on god, 5 on VIP and 6 on MVP.
I don't believe the server thing would work as it would just fill up the nodes.
I believe that god should get maybe a booster which they get once a month: the booster will make their server icon custom for 1 week. Just a suggestion but maybe it’s a nice one? It makes the price worth it for god
