It's pretty fair to say that the RSP in its current state is pretty bland, lacking features and really quite worthless. This is only a beta so please do not pay for a server if you are expecting anything more than very basic customisation. There are a lot of features being worked on. Its safe to say the feedback for RSP's looks very very bad in its current state so again I urge you to either wait to get one or you have no one to blame but yourself.
When these features are implemented I am sure the RSP will do our expectations justice, just reading this list is encouraging for me. It is a shame that the RSP's have been released and that they are full price, speak with your wallet and wait until they are worth paying for.
