Well, this is supposed to be for new comers to RPing too. Everyone starts out at some level, but everyone can also improve through practice. Moreover, another primary objective is to revitalize and attract more people to the RP section.
So locking people out right from the get go is IMO counter productive.
No opinions about the battle system as long as it's simple enough to grasp and use. XD
Just suggestions based on experience in the medium. I've no intent to take-over / run an RP here.
As for locking out players; having a free-form / entirely open RP that can accommodate late arrivals with established users is very hard to do. Even with a dedicated forum. Shin's stated he's not sure what he's doing. Having experienced / competent RPers will help him too. Newcomes can read / watch how things develop and take note for the next arc / episode/
