This was planned in a beggining but I decided to remove it because it would cause these problems:
1- There would be too much spam in the chat, as there are lot of Kit PvP ranks with long names and with VIP rank prefixes chat would be impossible to read!
2- Loads of questions about ranks would be made, and they would be confused with actual VIP ranks. Example: "ZAINOS HOW DO I GET COMMANDER? DO I NEED TO DONATE FOR IT? I CAN'T FIND THAT RANK IN THE STORE! HELP PL0X!"
3- It's actually not needed, you can view other's rank actually by doing /stats <username> or checking Leader Boards
