The amount of people still playing the game today that have been playing since December 2018 is quite small, and the percentage is just going down and down. Sticking around for 5 years, just to receive a title and gear (which can be obtained another way) is quite little. Beta testers honestly deserve more for their dedication.
This is a very controversial choice, but I think beta testers should have access to old limited cars, which release drop when a new limited drops. Since it would be impossible to obtain both the new and old, the old should be available at 75 or 50% the original price. Due to the fact a large portion of beta testers quit, the “value” of these limiteds will not drop a lot. Lastly, there shouldn’t be a robux option when purchasing these.
If the uproar gets over the top, then non-beta testers could access the old limiteds, however, at the same price as it originally was. This way, they get an option to choose which limited they want more.
