Only reason why JOB is harder etc is there is no Noob guide out yet combined with the fact that the "Shared" files are in Chinese (there may be some english) - so people will shy away from playing with this as they deem it too much work to get going (hurray I say).
The only bugs on JOB are in fact client side anyhow, combined with the fact the client is a lot easier to get hold of - means JOB is the server of choice - chuck your MIR2 1.4 in the bin now
