PC Graal needs to drop the tiered (Trial-Classic-Gold) system it currently uses and remove observer mode then sell the following one-time "upgrades" instead:
$10-$15 - Developer License (Allows you to use RC/be Staff on all servers)
$5 - Player Customization (Lets you change Community Name, and Heads)
Classic accounts would be phased out and be given Player Customization, active classic accounts (ones that logged on in the last 2 years) would be given the developer license.
