Actually the only thing that they did was to wipe the whole upg/epics which was creating pile of issues, they just branded it as a "new rohan" in order to try to avoid some lawsuits in case ballers would claim their money back.
All in all, wiping the epics allowed players to start again on a 'same ground' basis, allowed new players to play this game but overall it is STILL the same game. There is nothing new and GMs lied about it. Instead of branding it as a "new game", they should have branded it as "new server".
