Currently I see only you and a few others who are running around the forum and whining about unfair play, while I know multiple times more players who are not affected or who will adapt and continue to play. It's not possible to satisfy everyone, time to understand it. Some will go, some new will join.
If you prefer to delete your account instead of merge - your choice. But this is a business running, and opening new servers will always bring much more incomes than anything else.
I totally agree with your statement about new servers being big income providers. but it would have been a lot more courteous and professional to let the Zelos.us players know that their 40 day server was going to be merged to 11 year servers without having an option to merge to Zephyros.
