Like I said in previous posts reinforcement rates have to be ridiculously good to be able to go through 2 weapons and 2 sets of armour and 4 rings. I dont think they thought that far into this. As for the other servers I think ran and jin should merge together now and both rates together on 1 server. Ran server never has problems with forging or reinforcing and I really see absolutely no reason to want to play jin over isen or ran.
