My suggestion is to add subscription ranks for vip, premium, elite, sponsor, and supreme, such as a reduced price, like 20% of the actual cost per month. For instance, you can get supreme for $40 a month, or you can buy a lifetime rank for $200.
To be honest. I think renting ranks is cool, but not getting used alot. It would be cool to buy Supreme for a month to try it out. But.... I dont think alot of people will use it.
I agree with this. In addition, I think donor ranks for this would be even fewer because it would be a trade for in game items for sonething that would expire in 30 days.
