Here is my suggestion to what we change it too, I don't think the new suggestion would if we kept the current ranks' names the same. Also, I've changed the names around to more fitting places, and added new ranks.
1. Newbie.
2. Beginner.
3. Rookie.
4. Amateur
5. Decent
6. Average
7. Moderate
8. Intermediate
9. Semi-Pro
10. Skilled
11. Adept
12. Pro
13. Impressive
14. Awesome
15. Hardcore
16. Prestigious
17. Veteran
18. Expert
19. Sublime
20. Beast
21. Addict
22. Epic
23. Renown
24. Stardom
25. Insane
26. Stoner
27. Elite
28. Distinguished
29. Master
30. World Class
31. Nightmare
32. Phenomenon
33. Mythic
34. Royalty
35. Demonic
36. Emperor
37. Legendary
38. Demi-God
39. Diabolical
40. Godlike - I think for this rank you should be able to chose what ever colour or mix of colours you want.
Feedback would be appreciated, of course I removed some of the ranks that I thought just didn't really fit, like Getting There, which is now replaced with Decent. If these were to be accepted you'd of course just change the rank names, and who ever was at that rank would get that new rank.
