As already stated by Joe, it was a temporary server while heRO was undergoing maintenance. I think most of the community here doesn't want a high rate. No offense, but honestly..who wants a high rate, then comes to a 5/5/3 server?
I get what you're saying though. Have a low and a high. Well, that would probably (I'm assuming it does, I've never ran a server before) cost a lot more money and definitely more resources, not to mention..probably more staff, to help keep running, up-to-date, etc.
Also, please try to refrain from posting names of other RO servers please. It's against the rules and I understand you wasn't trying to advertise, but it is preferred you say, "Well, on this server I used to play on, they had a high and low rate" as opposed to, "Well, on *insert private server name here*, they had a high and low rate"
