I think they should look at the average diamond price on each server and before merging one server into another, x2 or x3 the gold on an account to match that of the server its going into.
Ex- Artemis has plenty of gold, and diamonds are average 120k each, indigo has little gold left, some players have quite a bit but that would be turned into peanuts if the same character was on artemis. Diamonds on indigo are average 40k each, so if indigo were to be merged into Artemis, I'd think every Indigo toon should get a x3 value to their gold in the move. It just makes sense for players who spend a lot of money on selling diamonds on lower gold servers like indigo, to get it all turned into nothing because of a merge.
As for same names, the one made first should simply stay, all those made after should be made to change their toons name.
These ofc aren't answers to you questions Heim, only my outlook on them and what I hope to see for equality.
