Aion Riftshade

I mean develop new version of Aion could be based on 5.8 but limited content to 4.6

Good thing about it is new graphics engine ,new stigma system.
Let us test this new beta server and give feedback what it should change.
And eventually when everyone happy about this testing server merge database into a new server.

Can you develop such as a server ?  It's a long term plan anyway I don't expected it finish soon but maybe a couple years from now ? 

There is no such version in the public domain. Perhaps it exists, but it is circulating among acquaintances that we do not have.
